Ok, I found my issue(s). I did not have imagex.exe in the same folder. Once I moved that in there, it was fine...well, it kept dying on me and I realized that I had modified the gimagex.ini file to be "Destination=.wim" so that the technicians don't have to wipe out "MyWim.wim", but I accidentally wiped out the drive letter to. It should've been "Destination=M:\.wim". It would start, then a cmd window would flash really fast and I kept getting glimpses of an error. After about 20 times, I put together that it was saying something about "not enough space"....so I figured I needed to look at the drive where the destination was pointing. That's when I realized that I messed up the .ini by completely removing the driver letter. Anyway, it's working.
