The binary mscorlib.dll version 2.0.50727.1433 was loaded from GAC where loaded mscorwks.dll version was 2.0.50727.832. So there were mismatch version of CLR binaries. Both the files should be at the same level. Hence, we renamed the existing mscorlib.dll at C:\WINDOWS\assembly\GAC_32\mscorlib\\mscorlib.dll and added the mscorlib.dll version 2.0.50727.832 to GAC from C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727.  Both the binaries were at the same level and we were  able to run the sample .Net 2.0 application successfully. Another  solution would be to install the .Net Framework 2.0 SP2 to upgrade all the core binaries.
