Calibre can't access my drives?

I just installed 0.9.41 on Windows 7 Professional.
When I try to add books and browse to Computer and drive I get an error

Location is not available
c:\ is not accessible
access is denied

I get this for all drives.

I am able to access my personal folder
C:\Users\Rod

This is my personal PC. I am admin on it.

I also get this error when I run caliber as administrator.
