Back awhile ago I upgraded my Nvidia drivers for my 280 GTX card. When I installed them, I lost my Nvidia control panel. I tried several times to install them and newer ones since. I still cannot get the Nvidia control panel to install or physx drivers to install either. The the other day I went to install Kaspersky and it keeps erroring out too. I keep getting a installer folder error. Come to think of it the Acrobat reader update always fails too. I get pretty much the same error if I try to manually install the Nvidia control panel or the physx drivers. Anyone else encounter this type of problem? I am not sure, but does win 7 have a repair feature like XP did? I never really paid much attention. Thanks for any insight.
