Crystal Reports for VS 2005 won't register on Windows 7 64 bit

851 Views

I am trying to install a VS 2005 app with Crystal Reports for .NET 2.0 on a Windows 7 64 bit OS. The install pack uses the CrystalReportsRedist2005_x86.msm merge module. During the installation several of the Crystal Reports DLLs do not register. The problem I am encountering is almost identical to an issue the was fixed in CR for VS 2005 SP1. The ReadMe doc for SP1 describes the problem as:

"Description: When installing a customized Setup project with the Crystal Reports for Visual Studio 2005 merge modules (.msm) on Vista, several COM components fail to register.

e.g. "Module C:\Program Files\Common Files\Business Objects\2.7\bin\ExportModeller.dll failed to register. HRESULT -2147010895. Contact your support personnel." If you run the setup.exe again and select repair, the installation will go on without any error, and the component can be registered. "

But, even after I do a repair (no errors are displayed duriing the repair) I still get an error when the app tries to launch the CR viewer. The error I get is:

"An error has occurred while attempting to load Crystal Reports runtime.

Either the Crystal Reports registry key permissions are insufficient or the Crystal Reports runtime is not installed correctly."

I have installed the CR for VS 2005 SP1 and still get the same errors.

Does anyone know what would be causing this?

Thanks for your help!
