Michael,
Simple advice with the disclaimer that this advice does NOT follow Microsoft's recommendations:
Always place all your VFP runtime files, FLL's, etc in your application's main folder (the same folder where you install your exe).
I've never had a problem with this approach.
BTW: I avoid the Common folder you reference like the plague because, as you're experiencing, 3rd party products (including your own<g>) can mess with these files. My thinking ... why have to suffer the additional support dependencies of having other apps mess with my application's files?
YMMV,
Malcolm (paranoid in NJ)
