Get Crystal Report XI R2 to work on 64 bit OS (win 2K3) web ActiveX viewer

Question

Can anyone help me with the issue below, I have been working on this issue for long time and have intensively researched the internet and tried out few solutions but non worked for me.
<p>
<b>Overview:</b><br>
I am working on an application that was build with a classic ASP and VB6 COMs. The COMs load rpt file, this would be the report template, then it loads a recordset into the rpt file and gets displayed on the web page using ActiveX viewer. There are few activities done by the COMs, varying from changing formulas, updating header and footer, suppressing sections to loading data. We are using crystal report XI release 2 with SP4 and application works fully ok on Windows XP and Windows 2003 on the 32 bit OS. Now we are trying to deploy the application on a 64 bit environment and we realise that we can only do this on 64 bit in a 32 bit mode. As we have VB COMs and they can only work on a 32 bit system. So I have done the following in order to enable our application to work and for the reports to run.
<p>
1)     Configure the IIS server to run in worker process isolation mode<br>
2)      Enabling the 32bit mode by running this command <br>
cscript.exe adsutil.vbs set W3SVC/AppPools/Enable32BitAppOnWin64 TRUE<br>
3)     Install our COM application and give the required permission <br>
4)     Install ASP files with rpt files and give the required permission<br>
With few attempts I managed to run our application on the 64 bit system using the 32 bit mode, but few reports still fails to display.
<p>
<b>Problem:</b><br>
I am unable to run and/or view crystal reports on a windows 2003 64 bit system.  I have turned on the 32 bit mode so I am able to run COM objects and I am able to run my application and view crystal reports but some reports still fails with no error message. The failed reports display the crystal viewer with no data no page but only the top bar with crystal controls e.g. export, move pages etc.
<p>
<b>Analysis/investigation:</b><br>
I run the same application pointing to the same database as my 64 bit (32 bit mode) environment and run the reports with some data and it worked fine, so I saved the report and tried viewing on my 64 bit environment with simple crystal preview page. Unfortunately it was same result as report came back blank in the viewer with no pages even though if I open that report the crystal application it will show me data saved with it. I have to say on my windows 2003 32 bit system that was fully working, I needed to turn on isolation mode in IIS 6 (i.e. turn off worker processor mode) in order to get all my reports working, otherwise I would get the exact same issue that I have with the 64 bit system. However in my 64 bit system I canu2019t turn on isolation mode, as the 32 bit mode option requires the IIS to be set with worker processor mode or none of the COMs will work.
<p>
So please could you help with any suggestion, or solution if possible.
<p>
Many Thanks

Hi Ludek
<P>
Let me clarify a bit about the issue we been have:<br>
For example we have report-1.rpt and report-2.rpt, both are very similar and in fact report-2 have a little bit more information than report-1. So when I install our application on a webserver in Windows 2003 32 bit system, with Crystal Report XI R2 developer edition + SP4, both reports work perfectly fine and application save the report and show it on the crystal report ActivesX viewer. So I made copy of report-1.rpt and report2.rpt with data and kept it a side.
<P>
Now I install our application that is the asp files and COM objects on a 64 bit windows 2003 and turned on the 32 bit mode to enable our COMs to work. I then run our application pointing it to the same database I used with the other OS, and I tried to run report-1.rpt and report-2.rpt, so report-1.rpt has failed with the viewer showing but no pages and only the controls. However, the report-2.rpt worked fine with data showing ok. So I copied the 2 reports I generated from the other OS and pointed my view report asp page to these rpt files, again same result report-1.rpt failed and report-2.rpt worked ok.
<P>
So I guess what I am trying to say is we are using the exact same COMs on both OS and to generate on both reports, also pointing to the same database using the same connection string. The result is one report is failing on the 64 bit machine.
<P>
Now when I try to export/save the report-1.rpt, the report that come with no pages, I get the error below, this is the same error I get if I try to move to different pages.
<br><br>CRAXDRT Error Occured on Server.70 : Permission denied
<P>
Please let me know if I can provide more information.

Many thanks
