>FWIW I only use the setup wizard to create a generic VFP app install set. I reuse that on every box. Then all I have to do is distribute the EXE and it's necessary files which I can do without any installer. I didn't have a large number of client sites though.

It sounds like you're installing applications to controlled office environments and such. My current project is essentially a shrink-wrapped product that's installed in people's individual homes and offices, so they have to have complete installation packages.
