Crystal XI will not run on Windows 7 (.NET 2.0 C# app)


Hi all,

I have an App developed with VS 2005 .NET 2.0 written in C# which calls a Crystal Report (developed with CR XI) for rendering.

When I deployed the App on Windows 7 Machine, any attempt to run the report is resulting with the following error:


System.TypeInitializationException: The type initializer for 'CrystalDecisions.CrystalReports.Engine.ReportDocument' threw an exception. --->

CrystalDecisions.CrystalReports.Engine.LoadSaveReportException: 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 for more information.


The application is running perfectly on windows XP Client.

the .NET 2.0 framework is installed on the WIndows 7 Machine. as well as Crystal latest runtime libraries.

CrystalReports11_5_maps.msm dated 9/16/2010

CrystalReports11_5_NET.msm dated 9/16/2010

CrystalReports11_5_NET_2005.msm dated 9/16/2010

resides in: C:\Program Files (x86)\Common Files\Merge Modules

What do I have to install on my Windows 7 PC to prevent this from happening.

Please Help 😊

Thank you.
