See Re: Unable to reinstall VFP7 Message #611697.

>I have found many threads and messages dealing with running VFP7 on Windows NT 4.0 TSE and/or Citrix. I was able to get the runtime files installed and can run my app fine, but I need to install native VFP and can't get past the Windows Component Update. It keeps telling me that SP6a for NT 4.0 is required and I have SP6a for NT 4.0 TS installed. Is there a switch that allows you to run the install and bypass the WCU?
