Microsoft Flight Simulator X is compatible with Windows 7 both 32 and 64 bit versions. You should be good with that since you are getting the Flight 1 LevelD 767.
Great, will order the MS X type then.
Probably won't go with the 767 right away, the FMS and MCP panel on the 747-400 and the 767-300 should be pretty simular and the purpose of this is to hit the right buttons and switches in the right sequence.
Noticed on ebay there is some differences between the MS Flight simulators, one was called the Gold version, one was not.
What is the difference if any?
All the best
