Unable to access nvidia control panel-

Last response: in Graphics & Displays
Share

I have a geforce-gtx-260 in my computer. I currently am playing the game Pool of Radiance:Myth Drannor (2001 I think). I believe it's normal aspect ratio is 4:3 which means there are black bars on the sides. Recently though, the screen has been stretched out and I can't get it back to the 4:3 ratio even when using a system restore.

I had this problem before and was easily solved by going to the Nvdia control panel and and select
"use Nvidia's scaling with fixed-aspect ratio". But when I click on the nvidia display control panel now it says, "the Nvidia display panel extension cannot be created.
Possible reasons include: Version mismatch. Reinstalling display drivers may solve the problem".


I've uninstalled my drivers, deleted the nvidia folder from the C drive rebooted and tried reinstalling the most up-to-date drivers and it failed. I tried the same thing with the previous driver and even tried it again with the newest beta driver from 2 days ago. All of them had a nvidia screen saying that installation failed.

I'm at a loss because I cannot access that nvidia control panel. Any suggestions for this extremely frustrating problem would be helpful.

Try running the driver cleaner I think you can find it on guru3d.com Then try a reinstall of the newest .70 drivers otherwise you will have to search through your application logs to see what is casuing the install problem thats never fun...

What computer and gpu do you have? Not all cards can use the reference driver.


You may just need to take ownership of the FileRepository folder if permissions have gotten whacked.



I have no idea what taking ownership of the file repository means but here are my specs:
