>I'm building a small application to up to 400 sites in the state of Michigan. I will be using DynaZip along with some other 3rd party applications. I wanted to simply use the VFP Setup Wizard to build distribution diskettes. Is this a good idea? I read with interest the Distribution concerning the DynaZip software. Should I also look at a third party package such as InstallShield?

Yes, definitely, if you install an installation like this, you will be better with InstallShield.
