How would I use that in RunOnceEx.cmd? Can't use multiple quotes in a REG ADD line...
Solution:
CODE
SET KEY=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx
REG ADD %KEY%11 /VE /D "ATI Catalyst Control Center" /f
REG ADD %KEY%11 /V 1 /D "%SystemDrive%\install\ATICCC\setup.exe /S /V\"/qb /norestart\"" /f
