Alt-tab-del should give the possibility to terminate all "running" versions. Then, all apps (Zone-Alarm, A-virus etc.) should be deactivated, too. The CD-Rom drive has to be configured to have no autostart etc. even if he uses a version without CD check.
Every clicking on the exe will start EU2 even if nothing happens, so he will have to cancel the ghost version first before trying anything else. That is, no other tweaks work as long as a ghost version is running. I recommend to try everything he tried before, but this time he should always make sure there´s no ghost version running. Chances are, the "right" solution was already among the things he tried, but success was prevented by a running "ghost".
I only remember that I managed to get EU2 running once I found out about the issue with the ghost versions. Took me quite some time ....
