It is normally not on the path

Well, The CreateWin32SnapShot (or something like that) used to give
one the file path and file name of all currently running processes

Latterly it just gives the file name, but I'm sure something will give
the lot

Realistically this is a 'boot strapping' operation, the OP's next
version will probably converse with the new version via
RegisterWindowsMessage so the Registry will be (correctly) redundant.

(well if I have anything to do with it, he'll just run both Apps and
they'll negotiate the update)

A nasty problem that I've kicked myself for not sorting out before it
bit me.
