There are plenty of other installers for VFP6, including the other freee one, Visual Studio Installer that can be downloaded from the MSDN Web site (msdn.microsoft.com/vfoxpro), and a wide range of third-party products. They won't address the issue of overwriting/uninstalling the VFP3 app - you'll have to write a bit of code that you run before handing control to the installer that checks for the VFP 3 version and deletes the files as necessary.
