Hi I think I'll probably buy the PMDG B747-400X but it's only by download and I don't know how it' work. I think we've a key to go on a page for the download and then download only 1 time. IT's correct? and the install folder .exe can we copy it in a CD or DVD if we change computer later??? Or someone know where I can buy it on CD? (I'm livin' in france at the moment so the shippement require...)

When you buy it, you get a link for the download. It's usually couple of days worth. So you can download it as many times as you wish in the meantime.And after that, you can burn the file onto a CD or onto any other computer. You can install it only with a working internet connection though. Before installing, a validation is required, that you do in the installer - though you have limited number of installs, you can reactivate the validation if you install it too many times. It's a good piracy protection IMO.PS. Sign your post with your name.
