If you’re working on SSIS with SqlServer 2005 version then you may encounter this error while working with Script Task. The Error message would be like -
And you package will not run.
Root cause reported by Microsoft support team -
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.
And Here is the fix for this -Download the hotfix package now.
This fix updates the SQL Server Integration Services 2005 (SSIS) scripting environment to work with a newly-released patch for a security vulnerability in the .Net Framework 2.0. Without this fix, any VB.Net scripts (Script Task or Script Component) in your SSIS packages may not execute, or work at design-time as expected.
After searching about the error I collected the above information to resolve the error. Hope this was helpful.
