Hi,
This is happen due to the following
This problem occurs because of a recent change in the common language runtime (CLR) workstation runtime for builds of the Microsoft .NET Framework 2.0. The CLR workstation runtime is named Mscorwks.dll. The change introduces a compatibility problem
for the Microsoft Visual Basic runtime engine that VSA uses. The Visual Basic runtime engine is named Vsavb7rt.dll. The problem prevents assemblies from being created correctly during the macro compilation operation. Because of this problem, existing packages
that contain compiled scripts do not run.
