Custome tool error: "Code generator 'ReportCodeGenerator' failed

After updating to Crystal Reports SP1 for Visual Studio 2010, when I try an create a new crystal report in any project, my visual studio locks up and I get the following error:


Custome tool error: "Code generator 'ReportCodeGenerator' failed.

Exception stack = CrystalDecisions.Shared.CrystalReportsException: Load report failed. ---> System.Runtime.InteropServices.COMException: Report engine not opened.

I've tried uninstalling crystal reports for visual studio 2010 and the runtime for both 32bit and 64bit, and then reinstalling but get the same error. Development system is sever 2008 sp2 standard edition 64bit, with Visual Studio 2010 Ultimate.

I'd greatly appreaciate any help, I've been at a work stoppage for the last week.

    I assume this is for a project you are trying to upgrade and the project uses embedded reports (strongly typed)? If so to resolve this error message, complete these steps:

    1. Click an embedded Crystal report in the Solution Explorer.

    2. View the 'Properties' dialog box for that report.

    3. Change the "VSDesigner" part of the custom build tool property string to "VSShell".

    4. Right-click the report and click 'Run Custom Tool' again

    Alternatively do not use embedded reports, particularly not if this is a web app. Use the .Load method instead.

    • Hi T.,

      Great that was the fix. The problem is CR uses those same variables which is what one must do to be Windows Certifiable. The problem is with old OS's the default was c:\temp so everyone simply continues to use it and there are file conflicts if it exists.

      Thanks again
