Hello! I am reinstalling all my FS stuff on my new PC and I have a problem when launching RC4 for the first time on Vista Ultimate 64bit.I have installed RC4 with no problems (did it "normal" and also as admin), updated it to 4.2 (as I'm still flying on FS9), launched it "normal" and as admin too, but when RC4 asks me to enter the key-code all I get when clickin the button is a RC4 crash without error messages after several seconds.Maybe anybody of you who could help me?! :-)Vista Ultimate 64bit, Intel Core 2 Extreme QX6700 Quad, 4GB RAM, RC4.2, FS9.1, FSUIPC 3.73Thanks in advance!Chris

is it possible the key you enetered isn't valid for your new installation? you can't use the same key as you did on the other windows installation. every installation is uniquejd

Oh...I tried the same key - didn't know that I need a new key for every reinstallation.Thank you very much for your answer! Just sent another key-request via mail... ;-) Chris
