Deploying Firefox With Multi Different Configs

Hello all, I am currently deploying Firefox to 3 different locations with 3 different config files. Right now i have and auto deployment package set up that sends it out to one site all on its own. That works perfectly. I have two other packages that are setup up to deploy on a script that i wrote to do the same thing and those work well but when i update the exe file that it pulls the install from of course it does not know that it needs to re deploy to all of the computers that it did successfully in the past. Whats the best way to clear that successful list out so it will attempt to deploy to the full list again?
