c:\Program Files\ Security in Windows 7

Question

There is a folder created and used by Microsoft Learning Products in the Program Files folder.  I would like to be able to copy additional courseware into that folder but when I run my application it gives me an unauthorized access exception.  Even though I can open up explorer and create the subfolder I need manually.  I've tried several ways to do this, but I think I'm missing ...something.  I guess I just don't know what I don't know.
