If I buy Acceleration, can I install it over FSX SP2? Is it straightforward?

Hi,I haven't done that, but it shouldn't be any problem. The Acceleration installer will install SP1, if needed. If you already have SP1 installed the installer won't install SP1. I would be very surprised if the Acc installer should handle SP2 in any different way, that is the installer won't install SP2 if it's already installed.Ulf B

Thx Ulf. The last thing to consider if Acceleration offers anything I need. I don't fly military planes in MSFS, I don't race.
