Error Registering ComPlus Components

I have solved the problem of Com + Registration problem on Windows 2003. "Type Library cannot be loaded".
The problem is with the path.The path C:\WINNT\Microsoft.NET\Framework\v1.1.4322 is not specified in the path string, Environment Variables.
Before ten days it was working so to know this we have downloaded the FileMon from www.SysInternals.com monitored the dllhost.exe.
The dllhost.exe is shown in the FileMon saying "mscorlib.tlb" Path Not Found.
Then I searched for the path and found out that C:\WINNT\Microsoft.NET\Framework\v1.1.4322 is not there in the path string
I have kept it there, then components are registered
