RDC and Windows Server 7


We have a classic ASP solution where we are using RDC to show "crystal report" reports on the net. This has been working for year now without any problems! The webservers have been mostly windows Server 2003, but also recently Windows Server 2008.

Now there is another operation system out there, namely WINDOWS 7, but here the crystal report viewer just shows the viewer, but without any report result. Exporting from the code to for instance PDF, Word, Excel it works fine.

The viewer work fine on Windows Server 2008, which i presume has many similarities to Windows 7.

The viewer is a active x control. Does anyone know what to do, because i assume that this maybe is a security issue....

    Only Crystal Reports Basic for Visual Studio 2008 (CR 10.5) and CR 2008 (12.x) are supported on WIN 2008 Server. Neither of these ships with the RDC. SO your app will not work on WIN 2008. For more info see;

    We also have this problem using Crystal Reports XI Release 2 with the latest Service Pack.

    With our next release we have to support Windows 7.

    Are there any statements from SAP to this problem?

    If anyone knows a solution please reply on this thread.

      Hello ronjac,

      I've issues with Crystal Report 9 on windows server 2008 R2. We are using classic ASP to call the report. Everything is working fine with Windows Server 2003 (32 bit). I'm testing this as we are in the process to migrate application to Windows Server 2008 R2 (64 bit). I did set up Application pool to 32 bit. We've installed Crystal Report 9 Advanced and Crystal Report Application Server 9. The issue is, Application is not displaying anything not even gray area.

      You have mentioned that it is working for you. I have not tried to change "rptserver.asp" file you guys are mentioning. What is the location of this file? Is this correct location (C:\Program Files (x86)\Crystal Decisions\Crystal Reports 9\Samples\En\Code\Web\Report Designer Component)?

      Can you please let me know what am I missing?

    Perhaps, I don't fully understand the issue, because

    we have XI R1 RDC running on both Vista and Windows 7.

    After reading a few more posts, I think the part that I

    was confused about was the "Viewer" component.

    We do not use the "Viewer" component, We export our

    reports using the HTML format, and then we view the

    reports with the CHTMLView class.
