This is going to be an un-believably stupid question for you guys to answer. I want to place my batch file in a folder called "Batch Files" in the applications folder. Now when i insert the command to run a batch file in my winnt.sif file as such %SystemDrive%\Install\Applications\Batch Files\Office2003.cmd which is in the [GUIRunOnce] it gives me an error saying that the line 49 is incorrect but when i replace the line and move the batch file to %SystemDrive%\Install\Office2003.cmd it works. Is it because the batch files folder has a space in the name?? I did say it was an easy one. Cheers
