Hi Tracy,

>Which vfp directory? the home() directory or the default directory when the app is loaded.

The home directory. Windows resolves a lot of paths relative to the location of the process image (EXE). That's VFP in this case. Executing an EXE with DO isn't loading the EXE as an executable, rather as an APP. For Windows it would be the same as Word opening a DOCX file.

It still seems that some of the references are resolved differently. This should be visible in the Procmon output. Have you had a chance to run your application with Procmon on a working machine and a non-working machine?
