ECHO Installing DaemonTools v3.47 ECHO Please wait... start /wait %systemdrive%\Install\DaemonTools\DaemonTools.msi /qn REBOOT="ReallySuppress" start /wait %systemdrive%\Install\DaemonTools\Daemonscript.msi /qb start /wait %systemdrive%\Install\DaemonTools\DaemonDriveInstall.DaemonScript start /wait %systemdrive%\Install\DaemonTools\DT.exe put this into an autoit script.. Run("rundll32 setupapi,InstallHinfSection DefaultInstall 128 .\DaemonTools.inf") & compile it & name it DT.exe thats the only other thing i can think of.. put it in same folder as daemontools.inf & if u dont know how 2 do this.. download autoit , open notepad.. place the above command into it.. name it DT.au3 & compile that .au3 file using autoit compiler, u can right click & choose compile script
