>We have some difficulties with the Setup Wizard provided by VFP 5. This potatoe head, when installed over an old version of our program, doesn't replace the EXE file but let the old one there ! And other incredible thing, the DLLs it has to install aren't changed, but they are added at the end of the old one. So a DLL is 1 Mo at the first installation, 2Mo at the second, and so on.

You must make sure the new version of the exe has a higher version number (Under the Build Screen, the Version button) or setup wuz won't install it...

Not sure what you mean about the DLL's not being changed, can you elaborate?

Also have a look at the MS kb article Q173992 "HOWTO: Uninstall VFP Application Installed by Setup Wizard".

Hope this helps...
