I don't know what you mean by ACTIVELY installed. Is this different to
INACTIVELY installed? If so, I would have thought that the active Euphoria
was the one that was on the PATH. That's why I said to scan the directories
in the PATH for ex.exe. If however, ACTIVE means "on disk" then just scan
every directory.
Also, what do you mean by "continue to search for ex.exe even after finding
it". If you've found it, why would you continue to search for it? Or do mean
you need to find all files that have the name "ex.exe"?
