hi,

A friend of mine had the same problem on his machine, while it worked on mine.
We solved it by using the inituser.exe program quoted somewhere in the msdn.
It creates a keyset for the administrator, which is needed for
CryptAcquireContext calls with the Microsoft Provider. I'm not sure where the
source for inituser is though?
