error on launch - .NET Framework Intializatioin Error

May 22, 2015 at 10:10 AM
To run this application, you first must install one of the following versions of the .NET Framework: .NET Framework, Version=v4.0

Would you like to download and install .NETFramework, Version=v4.0 now?

I have been downloaded and installed, but this error appear anyway. It's on Windows xp x32 (.net framework 4.0). Is it possible to recompile for .net framework v2.0 or v3.5? Anyway, fix this error, please!
