-> Do you have these 3 files (fidomsg.wcx, pxsrv.dll, pxnl.dll) in your
-> WC5 root folder on BOTH PC's (W10 & XP-VM)?  also do you have px.ini in
-> WC5/PXDATA directory on both systems?

All of that was there, and it didn't work, so I lookd at px.ini and it
had drive designator so I removed the d: and left the rest of path
intact and that did it.

Without you cluing me in on the px.ini file I would probably not have
discovered that for a long time if ever.

So I did get it working
