My presetup.cmd is like this, with the drivers already copied in a called paste DRIVERS, with the file SetDevicePath.exe in this paste, and WatchDriverSigningPolicy.exe in the CD\OEM\bin, but the drivers don't install. What is wrong? set tagfile=\WIN51 for %%i in (c d e f g h i j k l m n o p q r s t u v w x y z) do if exist "%%i:%tagfile%" set CDDRIVE=%%i: %SystemDrive% cd %SystemRoot%\system32 if exist setup.exe ren setup.exe setupold.exe if exist setupORG.exe ren setupORG.exe setup.exe %SystemDrive%\drivers\SetDevicePath.exe %SystemDrive%\drivers start %CDDRIVE%\OEM\bin\WatchDriverSigningPolicy.exe start /WAIT setup.exe %* RD /Q /S %SystemDrive%\drivers
