You're wrong, he did ask for it to be integrated. I was at least being forthcoming and saying that installing the hotfix upon first startup is not technically being properly integrated into the source as jeromerocks originally requested: (Keep It Simple Stupid) Sometimes, the best solution is to avoid fancy, schmancy batch scripts, etc etc and just burn two versions, that is one option. If you want to spend the time to create the script, tweak it, tweak it some more, test it on many systems, then be my guest, that's also another option. I was offering a pseudo-code approach to the problem. True, I wasn't giving you an exact recipe of how to do it but I figured it'd at least give you something to consider. Others can chime in with their opinions or thoughts, I'm merely one person who offered ideas while not chastising others for trying. Resources: Batch Scripting
