Crystal Reports for Dot Net framework 2.0

Windows 7

Whenever my insurance application tries to generate a report I get the following error:

CrystalDecisions.CrystalReports.Engine.InternalException:

Error in File C:\Users\ANDREM~1\AppData\Local\Temp\temp_e62652f0-d947-4816-88de-f07881cd3470 {A9C3C63C-F767-4236-8F45-A16E795A64F6}.rpt:

Operation not yet implemented. ---> System.Runtime.InteropServices.COMException (0x800003E7):

Error in File C:\Users\ANDREM~1\AppData\Local\Temp\temp_e62652f0-d947-4816-88de-f07881cd3470 {A9C3C63C-F767-4236-8F45-A16E795A64F6}.rpt:

Operation not yet implemented.

bei CrystalDecisions.ReportAppServer.Controllers.ReportSourceClass.GetLastPageNumber(RequestContext pRequestContext)

..

I searched the internet and found no solution.

Reinstalling Crystal reports for .NET framework 2.0 does not help.

All the required fonts are installed.

It worked for a few times and then stopped. Now not a single report is generated anymore.

Restarting or reinstalling the application does not help.

Does anybody know what is wrong here and how to resolve it?

Thank you very much for your expert opinion.

From your description I assume you are using .NET 2005 and CR 10.2 which bundles with .NET (?). Please confirm. Also, let me know if you have applied SP1 on your development computer and if you are distributing the SP1 runtime. Finally, is this a web or a win app?

It is a win app.

.NET 2005 and CR 10.2 which bundles with .NET used

SP1 applied and SP1 runtime distributed: CRRedist2005_x86.msi

"Crystal Reports for .NET Framework 2.0 (x86)"

the app is fully developed and works fine on win xp, vista and also most win 7 computers

on two windows 7 machines I get this nasty error.

Does anybody know what "COMException (0x800003E7)" means?

Could manual registration of specific dlls help?

Start with making sure the win\temp dir has read / write permissions.

Run [Process Monitor|http://technet.microsoft.com/en-ca/sysinternals/bb896645.aspx] and look for errors such as "Access Denied".

Compare dlls loading on a good win 7 computer and the bad one. Use [Modules|https://smpdl.sap-ag.de/~sapidp/012002523100006252802008E/modules.zip] for this.
