Hi all, I have a problem to install my nvidia driver ... I read on many website that i need to install my nvidia driver like an application ... so i tried to install like that .. extract from .exe, and then i used the next command line REG ADD %KEY%\003 /VE /D "nVidia Driver 6800GT" /f REG ADD %KEY%\003 /V 1 /D "%PP%APPS\nvidia\setup.exe -s -f1\"%PP%APPS\nvidia\setup_end.iss\" -f2\"%systemdrive%\nvidia.log\"" /f in runOnceEx batch file ... but the driver don't want to install ... (the driver is in WHQL) Anyone have an idea to correct ? Thx in advance
