David,

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.

>Be careful - there are crazy people like me that ignore the Setup Wizard (for good reasons) and use third-party installers instead. At that point, tracking .dll versions becomes much more important.
