>1. In Windows Explorer, go to the C:\WINNT\Installer folder and look for an .MSI file of about 71 KB, dated when you installed VFP7 on that machine. The filename will be something like 358ae7.msi. If you hold your mouse over the file, you will see a tip that has a line that says "Subject: Visual FoxPro 7.0 Baseline - English". If you don't get the tip, the same info appears under the Properties dialog Summary tab for that file.
>2. Rightclick on that msi file and select Uninstall from the context menu.
>3. Go to the \WCU directory on your VFP7 CD, and rightclick on bootstrap.msi, and select Install. This will reinstall the setup runtime files.
I have Windows 2000. My Windows directory is C:\WINDOWS. There is no Installer folder under that branch.
