Unable to register the library

Hello,

I have developed a S/W which works fine in windows XP environment but not in win 07.

I am getting below error.

Unable to register the library c:\windows\system32\stdole2.lib

Error accessing the OLE register.

I tried to register the library in many ways

1) Downloaded VBRegTLB6.exe to register the library.
2)Downloaded process monitor to find the Error's in the process
3) Downloaded subinacl.msi to solve problems during setup
4) Run with "Run with Administration"
5) Tried to run in comparability mode

Please tell me if there any other way.

How to handle this exception?

Thanks
