>Were the runtime files installed with a Setup Wizard created disk set, or were they just copied in place? If they weren't put in place by a Setup Wizard installation disk set, the first thing I'd suspect would be the runtime install, since the problem appears on multiple platforms and on different machines.

You might consider ordering the SP3 on CD from Microsoft for the nominal (~$20 for S&H to points in the US at least) charge rather than downloading it from msdn.microsoft.com/vfoxpro/downloads

I used Wise InstallMaker. I do have SP3 installed. Also, the installation works fine on a variety of other PCs.

I'll take a look at VFP6R.DEP and try the Setup Wizard for the runtime and see if that helps.

Thanks for the ideas.
