Thanks for the replies. %wpipath% worked out great for me.

Is there a substitute for the %cdrom% command line parameter? If so, what? I do not know what drive letter my removable drive will be after setup. It varies. Also can WPI be used from a fixed drive? I'm asking because file copying is much faster than using a cd or dvd

Outstanding work, spacesurfer. Now I can add to my xp switchless driver cab!!! Man the hours of my life I could of had back had I mastered switchless installers when XP first came out.

Is there an autoit script I can use to designate the install folder since I don't like to install programs to the default %SYSTEMROOT%\Program Files folder?
