As I see a lot of questions about installing AS2012, and as I've just made the installation without any problem, if I can help, here my experience (with W 7 - 64 bits) :- read the AS2012 user's guide, at least the introduction- download FSUIPC 4.751 and change the .dll file of your own FSUIPC (registered) with the 4.751 one- launch FSX and verify FSUIPC correctly installed (top menu bar of FSX)- quit FSX and download AS2012- unzip the files and install AS2012 (as2012.exe file) on any of your hard disks, due to necessary space for AS2012. You can choose a different disk than FSX (for me : F:\Program Files (x86)\HiFi\....., as FSX and ASE are on C:\)- launch AS2012 : it will find your FSX without problem, and, if you have, it will also find automatically your ASE license (except perhaps if you've changed e-mail address)- choose your parameters in AS2012, and launch FSX (with windows 7, don't use the button "Start FSX" of AS2012, you must always start FSX as an administaror, so, right clic)That's allBrian and Chris : great job !

Or people could just read the manual
