BusinessObjects.Licensing.KeycodeDecoder.dll could not be loaded

Hi we have developed an web appliaction using CR fro VS 2010 and framework 4.0 and upgrade the application to the release version of CR for VS 2010 (13.0)
In the developmet enviroment everithing works well, but when we install the web application to the client web server whe we try to access to our report developed using CR we have always a blank page with this js error "bobj is undefined", and when we watch to the event viewer we find also an entry with this message "the assembly BusinessObjects.Licensing.KeycodeDecoder.dll could not be loaded"
The web server enviroment is this one
-Win2003 server 32 bit with IIS6
-Framework 4 installed
-CR 13.0 installed
-no other CR version installed in the server
-Web application running with an application pool with an administrator user
Could someone help us?

By the way, after some research it looks like this error originates from the ReportDocument class's constructor. It appears that during this process is where loading of resources takes place and also some license checking stuff. In this process somewhere a FileNotFoundException results in this error showing up in the Windows Application event log.
I'm taking a look at the situations that may be causing this to happen but I can't find anything yet. My assumption is that this type of exception can be raised in cases where a file is not accessible due to permissions issues or hadn't been installed properly due to similar issues with permissions. Also I believe sometimes registry related errors can show up as FileNotFoundExceptions as well so I'm looking out for that too.
UPDATE:
It looks like the private ReportDocument.getMaxUsage() method that is called indirectly the first time a ReportDocument instance is created and this method appears to reference objects declared within the BusinessObjects.Licensing.KeycodeDecoder assembly such as the following types.
com.crystaldecisions.common.keycode.KeycodeException
com.crystaldecisions.common.keycode.KeycodeCollection
com.crystaldecisions.common.keycode.KeycodeDecoderFactory
These references are causing a FileNotFoundException when the assemblies are being resolved during the JIT processes and hence causing the errors that everybody has been seeing in their Windows Application error log. Since the exception is being caught and logged, this may not be negatively affecting the behavior of the new Crystal Reports for Visual Studio 2010 release but it does cause these error logs to pile up though and exceptions are also somewhat costly performance wise to raise so that could slow down the initialization of some apps just slightly.

"CRVS2010 Beta - BusinessObjects.Licensing.KeycodeDecoder.dll, cannot be lo

Creating an instance of "Report Document" writes an error in Event viewer.
I debugged and found following line of code:
CrystalDecisions.CrystalReports.Engine.ReportDocument reportDocument = new CrystalDecisions.CrystalReports.Engine.ReportDocument() generates error in Event Viewer as:
"The description for Event ID ( 4353 ) in Source ( Crystal Reports ) cannot be found.

The following information is part of the event: The keycode assembly, BusinessObjects.Licensing.KeycodeDecoder.dll, cannot be loaded."
I checked for SAP forums for this error message and the most of the times answer was that earlier versions of Crystal Reports if installed can cause this error. VM on which this issue is occuring does not has any other versions. We had uninstalled previous versions and installed CR VS2010 Beta2.
However, I don't know the impact of this error. Any ideas?
Thanks,
Gulab.

See my comments on the thread linked below. I've been getting mixed messages as far as whether the KeycodeDecoder assembly is actually used or not in CR4VS2010 but from my own analysis, the ReportDocument class does make references to types defined in that assembly. Whether these error log entries indicate something harmful or not I'm not sure but it does seem to represent the failure of proper licensing.

Hi there,
I am trying to use the Production Release of CR4VS2010 as found here:

If I try to use the Database Expert or Set the Database Location for a report VS2010 simply hangs.
If I look in the event log, I see a Crystal Reports error:

I have seen similar errors published with the Beta version and no real solution to them.
I have to have side by side versions of VS and CR together.
I am developing internal apps which will be deployed on servers where there will be side by side versions of VS
Can anyone help please???

Hi Ludek,
We're getting there... taking your suggestion about using the samples... they worked fine.
So I started digging deeper... I'm using code such as...
using (var report = new ReportDocument())
    report.Load(filename);
I need to do this because even though I have a "correctly designed" report when developing, the business might need to alter the layout at a later date. So I need to pick up whatever is on disk at the time.
So I look in a subfolder of the deployed project for the .rpt file.
And here's where things were going wrong at runtime...
There was a SILLY bug in my code such that I wasn't picking up the correct folder... i.e. File.Exists(filename) == false
So here is some sample code that demonstrates the problem:
namespace MisleadingExceptionConsoleApp
    class Program
        static void Main(string[] args)
            using (var report = new CrystalDecisions.CrystalReports.Engine.ReportDocument())
                report.Load(@"c:\temp\a_report_that_does_not_exist.rpt");
When you run this, you get:
-          ex     {"Load report failed."}     System.Exception {CrystalDecisions.Shared.CrystalReportsException}
+          [CrystalDecisions.Shared.CrystalReportsException]     {"Load report failed."}     CrystalDecisions.Shared.CrystalReportsException
+          Data     {System.Collections.ListDictionaryInternal}     System.Collections.IDictionary {System.Collections.ListDictionaryInternal}

+          [System.Runtime.InteropServices.COMException]     {"Unsupported Operation. A document processed by the JRC engine cannot be opened in the C++ stack."}     System.Runtime.InteropServices.COMException
+          Data     {System.Collections.ListDictionaryInternal}     System.Collections.IDictionary {System.Collections.ListDictionaryInternal}
          HelpLink     null     string
+          InnerException     null     System.Exception
          Message     "Unsupported Operation. A document processed by the JRC engine cannot be opened in the C++ stack."     string

+          Static members
+          Non-Public members
So to my mind, the InnerException here ("Unsupported Operation. A document processed by the JRC engine cannot be opened in the C++ stack.") is wrong and incredibly misleading!!! :O)
So that answers my runtime issue.
I still cannot open the Database Expert at design time... however, that is not a pressing issue for me right now.
But if you do have any ideas on how to determine the root cause I'd like to get that sorted too.
Many thanks,
James

The database DLL 'crdb_p2bbtrv.dll' could not be loaded.

I'm using Visual Studio 2008 to develop an ASP.NET application to display reports created using Crystal Reports XI.
We currently have a working VB6 application that employees use to launch reports written in Crystal Reports XI. My task is to rewrite the user interface using Visual Studio 2008 in ASP.NET and provide the reports on our company ASP.NET portal.
The reports that need to be launched are all existing reports written in XI. There is no VB code that defines data connection; it just launches the report in a report viewer.
Here is the VB 6 code:
Set CrystalApplication = CreateObject("CrystalRuntime.Application.9")
Set CrystalReport = CrystalApplication.OpenReport(grsReports!ReportFile)
crViewer.ReportSource = CrystalReport
crViewer.ViewReport
Very simple!
Now this should be simple to reproduce in ASP.NET page; 30min top.
Dim crystalReport As New ReportDocument()
crystalReport.Load(q.ReportLoc)
CrystalReportViewer1.ReportSource = crystalReport
I created the page threw it up on the server and everything looks fine. When the user selects a report they are presented with a box that says enter values. They enter the date range and select OK. Then BOOMB!
The error message u2013 u201CFailed to load database information. Details: The database DLL 'crdb_p2bbtrv.dll' could not be loaded. Error in File C:WINDOWSTEMPvoucher reprint by voucher {AE5F62B2-1704-428D-8DCD-4BD83001BF49}.rpt: Failed to load database information.u201D
When I open the report in Crystal it works just fine and I dont get any errors, even on the server
I installed process monitor on the server
1. I've deployed the CRRedist2008_x86.msi (BootStrapper) on the server.
2. Installed Crystal Report XI on the server
3. Installed pervasive PSQL

Install the Btrieve database engine on the system with the Visual Studio .NET application. How do I do that?
Thank you

Hi Larry,
The problem is you originally used the CR Basic version which is included with VS 2008, cr version is 10.5. So what you are doing is going backwards in CR runtime version.
Next problem is CR Basic for VS 2008 does not include the native Btrieve driver and the one included in the XI runtime will not work in VS 2008. VS 2008 and CR basic only supports the basic ODBC, OLE DB and few others drivers...
When you downloaded the trial version of CR 2008 use Service Pack 3 full version and rebuild your app with the updated 12.3.x.x runtime, 12.0.1100.x and 12.0.2000.x assembly versions. And when you do install CR 2008 SP 3 select the custom option to manually select the native btrieve/pervasive driver, it's not installed by default. Now your application will spefifically look for CR 2008 rutime, if you don't update by rebuilding the app it will continue to use the 10.5 runtime.
Now when you build your deployment package also use the Service Pack 3 Redist MSI package, it will include the native driver.
If you don't purchase CR 2008 your license will run out in a month and your users will not be able to continue using your app.
If you don't upgrade your only option is to convert your reports to ODBC and then verify you are not using any CR XI specific features, they won't work in CR 10.5 runtime.
Hope this clears it all up for you?
Thank you
Don

Failed to load database information DLL crdb_p2smapi.dll could not be loade

Hello,
Iam using Crystaldelivery to view mij crystal reports.
I have made a report to read in my outlook agenda.
The design of the report is made in Crystal report XI release 2.
First when we open the viewer you can select the parameters and then comes the error message.
Now when i want to view the report in Crystaldelivery or any other crystal viewer (i tried with more viewers) i get the message:
Failed to load database information.
Details: The database DLL crdb_p2smapi.dll could not be loaded.
Error in file: PATH TO THE TEMP FILE.rpt:

Can somebody help me with this?
What makes this error to come up and how can we get the message away and we can view the report.
thx

Well, you are still not giving enough info to suggest things so I recommend purchasing a support and working with a Support engineer to resolve the issue. It's obvious information requests is being lost here so to get this resolved please contact CIC and purchase a case.

Failed to load DB info. Details: DLL 'crdb_oracle.dll' could not be loaded

Hello anyone who can help.
Reports were created using a full version of Crystal Reports 2008, version 12.2.0.290
I am trying to show the reports in a VS 2008 web page but I keep receiving the following error.
"Failed to load database information. Details: The database DLL 'crdb_oracle.dll' could not be loaded"
Googling the Internet I found several things to try but nothing has worked.
1. Made sure the crdb_oracle.dll was in the path
2. Copied the crdb_oracle.dll to
C:\Program Files\Business Objects\Common\2.8\bin
and to
C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86
3. Granted full permission to ASPNET to the folders in which crdb_oracle.dll resides.
4. The oracle client is installed.
I am not really sure what else to try at this point.
Any help is greatly appreciated.
Thanks
Mike

Here is your problem:
2. Copied the crdb_oracle.dll to
C:\Program Files\Business Objects\Common\2.8\bin
There is a reason for why that dll is not included with Crystal Reports Basic for Visual Studio 2008 (10.5). E.g., CR 10.5 is a bundle that comes with MS Visual Studio. Oracle being a competitor of MS...
Anyhow. Tips on how to proceed:
1) Use ODBC or OLE DB AS opposed to a native Oracle connection
2) Use the CR 2008 assemblies not the Crystal Reports Basic for Visual Studio 2008 assemblies
3) You could even consider ADO .NET Datasets - but that depends on other variables (structure of the report, amount of data, etc., etc.)

Siebel exception - SSCASVBC.dll could not be loaded

We have many CORBA servers written in C++ running on SOlaris box. They connect to Siebel Corba Object Manager running on windows server and fetch the business components.
I am getting error Siebel exception 4096 "SSCASVBC.dll could not be loaded sometimes when trying to get a business component or sometimes when invoking a business method. If I bounce all the servers the error disappears for 3-4 days and after that again the problem starts. What can be wrong. I do not know much of Siebel. I do not even know where to look for logs and how to enable Siebel logs or CORBA logs. I guess currently no logs are getting generated. Can someone help me please?
siebel version is 6.3 and we are using visibroker orb for CORBA

q1: is there a way to tell visual studio 2005 not to produce a .net dll?That's not a Java question. It is a Visual Studio 2005 question. Ask the vendor.
q2: i tried compiling the code in vc++ 6.0 but got a bunch of "files not found" errors.Then you need to fix them. Again this is not a Java question.
i don't think the sdk is even compatible with vc++ 6.0. is there an alternative?Once again that question should be directed to the vendor.
MSDN is probably your friend here.
has anyone successfully compiled c++ code with gdiplus stuff (graphics, etc...) in vc++ 6.0?Many times.

NiScope Initialize.viThe specific niScopeDAQ or niScopeDMF dll could not be loaded.

I am getting this error when I try to use both IVI-SCOPE and NI-SCOPE in TestStand. I make sure to close each reference before I use the next, but it seems like whichever one is called first will not release its reference unless I reboot the PC. I wrote a LabVIEW VI that initializes the scope using IVI, then closes it and opens it wth NI-SCOPE and this seems to work fine However, when I try to execute a sequence in TestStand that should effectively do the same thing, I get the following error when calling niscope Initialize.
Details: "niScope Initialize.viThe specific niScopeDAQ or niScopeDMF dll could not be loaded."
Error Code: "-1074118608; User-defined error code."
I need to use both because the IVI drivers do not support phase measurements. If anyone has any suggestions to fixing this, I would really appreciate it! I'm using LabVIEW 2013 and TestStand 2013 and my scope is an NI PXI-5112.
Thanks

Hi K_Joy,
Thanks for the reply. The TestStand sequence uses the built-in IVI steps to interface with the scope via IVI drivers. The NI-SCOPE version uses TestStand Action steps with LabVIEW modules that call VI's located in the C:\Program Files\National Instruments\LabVIEW 2013\instr.lib\niScope. I uninstalled NI-SCOPE version 4.1 and reinstalled version 4.0.5, which seems to have resolved the problem. However, now when I launch the NI-SCOPE Soft Front Panel I get this error: "The Soft Front Panel could not launch because an error occured while trying to open an application reference." I can live without the Soft Front Panel for now, but on top of that I am now getting this error when using my DAQ module (a PXI-6221 M Series DAQ) : "Driver cannot complete the route, because the only way to make the route requires a trigger bus line, and no trigger bus has been configured in MAX for this device." I'm currently attempting a repair installation of NI-DAQmx MAX Configuration Support 9.7.5. Right now, I'm more or less just reinstalling differenct things because I don't know what else to do, so any insight you can offer into any of these problems would be greatly appreciated! I've included both the TestStand sequence and the LabVIEW VI that I used to test the IVI vs NI-SCOPE problem, in case you're interested.
Thanks

Hi guys.The post title explains the problem...I'm using Crystal Report XI : Developper with Windows Server 2003.I need to display reports over the web, so I'm using the Crystal Report ActiveX Viewer.All is working fine for now, except the following : When I try to show the report, I only see the Viewer's border, with the viewer empty, and on the top, its written : Failed to load database information. Details: The database DLL 'crdb_odbc.dll' could not be loaded.
I searched my computer, and I found many different crdb_odbc.dll(I used many different versions of Crystal Report), they all are in the Common Files folders, and I tried to register it, but since there is no Entry, I cant register it. I also un/re-installed Crystal Report, both on the server AND on the client machine, and I keep getting the same error message.So I'm kinda stuck now.. If anybody knows where I should head first, to get over this problem, it would be very nice.Thanks.François BoivinSTAS, Analyst Programmerwww.stas.biz

CA Forum: Data Connectivity and SQL
when you set up your ODBC connection what type of connection did you create. Does it work from any machine ?. You might want to try adding another ODBC connection to the Windows Server, Chose System DSN (If that is appropriate for your environment) and try the openlink generic (Again If that is appropriate for your environment) Whatever you call this connection, you will need a clone on the server side as well, same name, same case, same everything.... Not sure if this will help, but I had some situations were I got a similar error, and doing the above fixed my problem.... ( I am using SQL server though, so....)

The data base DLL 'crdb_dao.dll' could not be loaded.

This has been posted in other threads but I've not seen a final resolution.
I used VS2008 to create an application that includes Crystal Reports and One Click in VS2008 to create a runtime system to distribute my application. The system installs and runs properly on a 32 bit system but fails to run on a 64 bit system. I get a message on the 64 bit system that says
The data base DLL 'crdb_dao.dll' could not be loaded.
I cannot find the crdb-dao.dll module on the 64 bit system but can find it on the 32 bit system. Can anyone tell me how to overcome this problem?
Thanks!
John

Hi John,
Moved to .NET Developer Forum. As noted in those other threads, there is no 64 bit version of the DAO driver. Your only option is to use ODBC or OLE DB.
No plans to create one because I don't Microsoft does NOT support their Access driver in 64 bit modes. See this Microsoft article on the history and supportability of DAO:
http://msdn.microsoft.com/en-us/library/ms810810.aspx
In this article it states:
There is no 64-bit version of the Jet Database Engine, the Jet OLEDB Driver, the Jet ODBC Drivers, or Jet DAO available. This is also documented in KB article 957570. On 64-bit versions of Windows, 32-bit Jet runs under the Windows WOW64 subsystem. For more information on WOW64, see http://msdn.microsoft.com/en-us/library/aa384249(VS.85).aspx. Native 64-bit applications cannot communicate with the 32-bit Jet drivers running in WOW64.

The database DLL 'crdb_query.dll' could not be loaded

Hi Experts,
We are facing the following problem on windows 2008 64bit machine with crystal reports 2008 and ODBC connectivity.
We are upgraded our production server OS to Windows 2008 64bit machine,After upgrade some of the crystal reports are not working and throughing the following error
Failed to load database information.Details: The database DLL 'crdb_query.dll' could not be loaded
Not able to find the exact reason.There is no difference between working and non-working reports.
On server we installed Crystal reports 2008 developer and runtime version.Our application is build on .net and to connect to database from crystal reports we are using ODBC connectivity and our database is oracle
Any idea how to resolve this one?
Thank you.
Edited by: venkat_crystal on May 18, 2011 6:57 AM

CR 2008 and it's runtime is 32 bit only. Make sure your database client also is 32 bit and you added your DSN using the 32 bit ODBC Administrator.
As long as you use Service Pack 3 it should work. windows 7 was added to SP 2 and 2008 is it's matching Server OS so it should work.
How did you distribute the runtime?
Thanks

The correct verision of the database client for this database type miight not be installed.

Convert your reports to use ODBC, that should always work.
You did not say what version or anything else but it's possible that driver is no longer shipped.

The database connector "Crdb_p2bpfx.dll" could not be loaded

Hello,
I received a new laptop, and now my reports no longer work. I get the error "The database connector "Crdb_p2bpfx.dll" could not be loaded" then several others that follow. I have ODBC connections setup that test successfully and I connect to the database via other means. I am using Crystal Reports Professional version 11.5.12.1838 on Windows 7. I have seen a few other posts regarding this file, but nothing that seemed to address my particular situation. Any help would be greatly appreciated, Thank you.

No references. Only from the DB driver name it tells me you are using a report that was originally created off that Third Party DB driver. How to get around it is something we don't have any details on nor can we. Search using Google, it may tell you something..
After searching I see it is the DataFlex Driver: http://www.pfxcorp.com/faqcrystal.htm
PFXcrystal FAQ
How can Crystal Reports 9, 10, XI, XI R2 and 2008 work with PFXplus data?
Crystal Reports can access Powerflex database directly, connecting via PFXcrystal; or through ODBC, connecting via PFXodbc.
Contact DataFlex for assistance... They were an OEM Partner or had the source code. So somewhere you got those reports from their product and or package...

NiScopeDAQ or niScopeDMF dll could not be loaded

Hi there,
We have a NI PCI-5112 installed in an inductrial PC. The OS is Windows 2003 server. After power up, the call to niScope_init returns an errorcode of 0xBFFA4030, the error message associated with this errorcode is "The specific niScopeDAQ or niScopeDMF dll could not be loaded.". After going to "Measurement & Automation" and opening "My System"->"Devices and Interfaces"->"Traditional NI-DAQ Devices"->"NI 5112 for PCI (Device 2)"->"Test Panels...", the device works with our niScope_init call. We tried to uninstall, reinstall the NI software, it didn't help.

Hanshi,
NI SCOPE is not officially supported by Windows Server 2003. Some customers have been successful using other NI drivers such as NI DAQ with 2003 server but unfortunately it is nothing we can guarantee will work as there has not been extensive testing to indicate this. You may want to try using the latest drivers available for your device before assuming that it is incompatible. The latest drivers are available for download at

You may need to upgrade versions of other drivers such as NI DAQ before installing a newer version of NI SCOPE. The requirements for the driver can be found in the readme file included with the driver. I hope this resource helps!
