>Pardon my ignorance, but when I install a 5.0 app, I have to include VFP500.dll & VFP5enu.dll in the installation. How does the 5.0 app locate it's required runtime files?

Mike, just take my word for it; ypu need to register the files. I'm not getting into this particular waste of time; simply copying the runtime files into a search directory or the app directory is not an adequate install, and not all VFP5 operations will work properly. There are also more files involved than those two. Good luck.
