Here's my setup: if exist %systemdrive%\windows\system32\atiddc.dll goto atiyes goto atino :ATIYES ECHO. ECHO Installing ATI Control Panel for Catalyst 3.7... unrar x %systemdrive%\install\ati_cp37\ati_cp37.rar %systemdrive%\install\ati_cp37 start /wait %systemdrive%\install\ati_cp37\Setup.exe -s -f1"%systemdrive%\install\ati_cp37\setup.iss" goto finish :ATINO goto finish I assume this checks if an ATI card is present and only installs the Catalysts if one is, which is smart. Is there a similar way to check for an nVidia card?
