Hello!
I recently installed Vista x64 Business on my macine (specs are below).
I downloaded the newest drivers directly from NVIDIA:
GeForce Release 178
I started the installation ,everything worked fine, BUT...at the end of the "green install bar" it stopped for a few minutes and then finished saying "The software didn't not make any device changes" or something like that. I was puzzled since those are WHQL drivers.
When I closed the install program, Vista came up with the standard:"This program might have not installed correctly." Then I was really worried.
I reinstalled Windows again just be sure but I got the same thing.
Well, after that second take, I restarted the computer, and everything worked fine (!!!)
Drivers were up, properly displayed in device manager ,everything working. Since then I'm running Aero, playing games, 3dmark vantage went well...
I shared this with you just to see if anyone had any similar experience?
