I'm running Vista Home Premium 64-bit and I can't even get the setup program to open.
Can you be a little more specific at how you performed the install?
Were you logged in as a normal user or with an Administrator account?
If you were logged in as a normal user, did you use the "Run as Administrator" option?
Do you have UAC on or off?
Did you use a compatibility mode setting?
Any other details you can provide would be great.
