Class not registered error, when open HTML files.

Hi guys, recently I've been facing this problem, everytime that I try to open a HTML file it shows the error message "class not registered", I've tried reinstalling and yet no luck, this only happens with firefox because I also have IE 10 and it works with that one but you know, I love firefox so I want to open them with it.
Additional Info:
I'm using firefox 20.0.1 on Windows 8

Try to redo the default browser setting and temporarily set another browser like IE as the default browser.

Class Not Registered error when opening COM+ Applications folder

Hi,
This question was originally posted in the Microsoft Community / Win 7 forum, but I was asked to post it here.
As you can see below, I'm getting Error Code 80040154 - Class Not Registered when clicking on COM+ in Component services.

I took a look at the event logs but couldn't glean much information from them.
I also have issues associated with MSInstallVSSProvider when Uninstalling / Installing Norton Ghost 15. Not sure if they are related or not.
Below are the errors I get when Installing Norton Ghost 15. This app had been loaded on the PC earlier with no problems whatsoever. A few months later when launching the app, I got several error messages. Couldn't resolve them so I thought I would uninstall
/ reinstall. That's when I started seeing the MSInstall errors, which lead me to the Component Services area.

I suspect a registry cleaner (GlarySoft) is the culprit here. My mistake was not backing up the registry before running the scan. This won't happen again.
Thanks,

Hi,
In the event error, can you read what {GUID} encounters the error message? Please also let us know the full error message.
Based on my search, this issue can be caused by the incorrect registry permission settings.
Please launch Registry Editor and navigate to HKEY_CLASSES_ROOT\CLSID\{GUID} to verify the permission settings.
If it does not work, you may run Process Monitor to check what process encounters this error.

"Class not registered" Error when running Windows Explorer

Hi,
I've been having trouble running Windows Explorer + any related programs (Control Panel, Internet Explorer, etc.). Whenever I try to run such programs, a popup containing the following comes up:
C:\Users\<username>\AppData\Roaming\Microsoft\Windows\Start Menu
Class not registered
Any help? I've tried using a registry cleaner, and the command regsvr32 ExplorerFrame.dll didn't work. I don't recall installing anything, and everything else seems to be fine.
Thanks in advance.
EDIT: I've tried System Restore, didn't work.

uninstalled and reinstalled photoshop CC and cannot resolve this issue.
any time i open a .jpg file in photoshop, I get a "Could not complete your request because the file was not found."
the file is obviously there, so i'm assuming its missing some sort of plugin, which i thought would be resolved when reinstalling photoshop.
very frustrated and not sure how to fix this.
running OSX mavericks
please help

used bridge, didn't work.
tried right-click, double click..open in program.
same error.
files work in other adobe products.....
only way to get a jpg in there is to "paste" it in.

Excel Viewer: Class not registered (error -2147221164)

Hello,
I am using the Excel examples shipped with Labview 8.21 to read from an Excel file and this works well. Now I need to do the same but on a PC that does not have Microsoft Office or Excel installed but only the free XLVIEWER (Microsoft Office Excel Viewer). When I try to change the ActiveX class of my reference to feed the 'Automation Open' vi I get the Class not registered (error -2147221164) although I can browse down to the XLVIEWER.exe and select it. Then I thought that maybe XLVIEWER had no ActiveX to communicate with other application; I thus installed a package called excelocx.exe, rebooted the PC but that did not change anything. I am still stuck with the same error.
What am I doing wrong?
Thanks a lot,
Christophe

Please find attached the VI I am using together with the XLS file that I try to read with Labview on a Pc that does not have MS Excel installed, only the XLVIEWER.
OpenOffice is not supported in our company so cannot be considered as a valid solution.
Thanks,
Christophe

Class Not Registered error upon using MS Office Report

Hello,
Using LabVIEW 2010, I've just installed the Microsoft RGT trial from NI, along with the Office 2010 trial from Microsoft. Upon trying to drag the MS Office Report VI to my block diagram, the configuration dialog appears but immediately an error dialog shows up over top, with a Class Not Registered error. Attached is the screenshot. If I close the error and try to configure the VI for a basic Excel report, I get a file-not-found error in reference to the Excel template, which I have verified is indeed at the target path and opens with my version of Excel just fine. Any ideas how to get past this error?

Hello,
It sounds like you have to reinstall the RGT. Have a look at this documentation.

Class Not Registered : Error -2147221164

Let's see if anyone can solve this one :
I have a *.tlb file, and I'm using the "Automation Open" vi to open the file so that I can invoke methods on it.
This vi is giving me the following error "Class Not Registered : Error -2147221164". This is only happening on one of my computers.
Can anyone shed any light on this one?
Thanks, Gene

I am assuming from your response then that you have tried to use regtlib anyways. All I can find on the error says to register it again. Maybe try to un-register it and then re-register it. Here is a Knowledgebase that talks about the methods to register it.
How Do I Manually Register Type Libraries, ActiveX Controls, and ActiveX Servers?
One thing is to make sure you are logged in as an administrator. Also what version of LabVIEW and are you running this as a VI or an exe?

AxInterop.AcroPDFLib.dll throws "Class not registered" error on 64 bit OS

I have an vb.net application which uses AxInterop.AcroPDFLib.dll to open PDF files. The application works fine on a 32 bit operating system. But when the same application is accessed from a 64 bit Operatiog system, it throws error "Class not Registered".
Am i supposed to use different version of AcroPDFLib.dll for 64 bit OS.
I have Acrobat reader 9.1 installed on 64 bit OS machine. Is there any newer version of SDK/dll which will fix ths problem.
Please let me know solution for this problem.
Thanks in advance.

I am pretty sure if you compile your client application as x86 itwill work fine....you are probably compiling it with the configuration set to AnyCPU. The application loads up as 64bit or 32bit depending on the OS when set to AnyCPU. You want to force it to load as 32bit by compiling as x86. That way the app runs under WOW and loads the AcroPDFLib correctly.
Hope this helps

Class not registered TSLV when attempting to run a report in CE10 w/ sp2

I'm running Crystal Enterprise 10 with SP2 and receive the error message when I attempt to either schedule or run to screen any report.
Class not registered TSLV
Unable to retrieve object
Class not registered-TSLV
I have reregistered all the .dll and .ocx files related to Crystal but I still receive this error message.
Thanks,
Gregg

there was a conflict between the local Crystal Reports and Crystal Server client tool components. I had to uninstall and reinstall both solutions and was required to install and Crystal Reports related software and service packs first. Then the Crystal Server components installed with no issues.

Class not registered error in Visual Studio 2003

Post Author: LenReinhart
CA Forum: .NET
I have an report that has been running in an application for the last couple years. There is an error in the application that I fixed, but now the report is not running against the production database and I wanted to look at a report in the editor and double clicked on the report in Visual Studio 2003. I got an error pop up "Class not registered" but that was it, no option to enter a registration code or anything. I had previously registered but tried going through that process and was told that it had been previously registered. I developed this report on this machine, so I am wondering if some patch that I applied caused this problem. It has been awhile since I have opened this report in an editor.Any light you can shine on this would be appreciated. Thanks,Len

Typically that error is referring to a COM dll that is not being loaded because it is not registered on the system. Usually, that error message will give you a dll name, or a PROGID, or something.....was anything else provided in the error?
In order for a file to be unregistered, something might have been uninstalled (or a failed install) that could have caused this issue. I did a search in kbase and found a article that may help, at least it refers to a dll that you can try to register.
Perhaps doing a reinstall may resolve the error.
