Question

Hi all, I have a production server machine with 64 bit hardware with 32 bit Microsoft Windows Server 2003 Enterprise Edition Service Pack 2, Crystal Report 10, dot net  framework 2.0 installed on it. When I run my web application and try to get the report I got following exception:

-----------------------------------------------------------------------------

Server Error in '/Si' Application.

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

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

Please install the appropriate Crystal Reports redistributable (CRRedist*.msi) containing the correct version of the Crystal Reports runtime (x86, x64, or Itanium) required.  Please go to http://www.businessobjects.com/support for more information.
