Crystal Report Problems solving with Visual Studio 2010

CRVS2010 Beta - file not found error crdb_adoplus.dll  

An error when running the product when have installed CR 2010.

"Could not load file or assembly 'file:///C:
Program Files

SAP BusinessObjects Enterprise XI 4.0
win32_x86
dotnet1
crdb_adoplus.dll' or one of its dependencies.

Solution

Setting the useLegacyV2RuntimeActivationPolicy flag to True does "solve" the problem. However, that is a hack and not a true fix. In trying to create a purely .NET 4.0 application, the end user shouldn't have to add this flag to get an application to work. Hopefully someone at SAP will note this and fix it in the core Crystal Reports functionality before the final version for VS 2010 is released.

Add following section to your config file and it may resolve the issue. <startup useLegacyV2RuntimeActivationPolicy="true">   <supportedRuntime version="v4.0"/> </startup>
