Hi there,I got into serious trouble with the 747-400 queen of the skies software. Due to some unknown reason something went wrong with FS9. So I uninstalled the program to start from scratch. When I went to add/remove software, to do the same with PMDG 747-400 I got "the installed version of the application could not be determined. the setup will now terminate". I get exacly the same message after reinstalling FS9 and PMDG.So I started with regedit and cleaned the regestries using "pmdg" "747-" and "747-400". After going over the whole installation of FS9 again, I still obtain ""the installed version of the application could not be determined. the setup will now terminate". I'am not a computer illiterate dough I'm stuck. Please help.Vickster_be

Vick,It sounds like you somehow deleted a whole heap of PMDG related files manually before you tried to uninstall using the remove/install software control panel. Drop me a note at [email protected] and I will see what we can do to straighten things out.RegardsPaul Gollnick :-cool Technical Operations/Customer Operational SupportPrecision Manuals Development Groupwww.precisionmanuals.comhttp://www.precisionmanuals.com/priv/img/forum/sig_pmdg.jpg
