Hi Pete,
Finally, I think I find the problem, after trying and testing again, may be this is a coincidence, but now everything does work:
In fact, two days ago, I desactivated the antivirus, but not my firewall when installing AS2004.
So, yesterday before sending you the FSUIPC reg file, I decided to re-install first FSUIPC, then AS2004 with the firewall off.
In consequence, unlike before, when intalling AS2004, new installation windows (with repair, modify an remove options) appeared. And then the version of AS2004 (B175) is now properly shown.
I cannot explain this "miracle" :lol: ! Do you think it is a FSUIPC related problem or AS2004 installation bugs ?
Anyway, thanks for your support
