I'm using fsx boxed. Tried changing the registry for secdrv and still doesn't work

I have it in download format for fsx and tried allowing full control for the install .exe and the fsx install folder, but I'm still getting the install error.

I have just bought wilko 737 pic evo and cannot get it to install. I have the correct product key but i get error "2" whenever i try to install Windows 7 64 bit
