Hi jdHave installed Vista on my machine and whilst I am still using FS9 I have tried to install from CD rcv4 and 4.1,4.2.When I go to paste my key ,and then press to conclude the process nothing happens.I have tried the FAQ route to no avail.Anyone any ideas spelt out in simple languageRegardsNorman Bowman

run rcv4.exe as administrator.right mouse click the icon shortcut, or the .exe, and "run as administrator"jd

Hi jd,I have tried running exe. as administrater without success.My pc was upgraded to vista and it will not allow me to register using either of my codes,my original one and a new one when I purchased 4.3 by download for FSX in a couple of weeks.Which code should I use for this vista/FS9 version loading by CD and upgrades to 4.2?RegardsNorman Bowman

I'm in the same boat too. I tried to run as administrator. But still couldn't enter the key code.

send me your keyboard.dat file, and your product id. jd
