Good question, I wish I could get my hands on my CD copy of Aces but it is in storage
Do you have the 1.2 patch?
I think if you get the game running it will be easy to tell which version it is by pressing ctrl-v while running the simulation. The unpatched version will be: Version sim 4.27, shell 4.7 (AOD v1.0). The 1.1 patch will upgrade AOD to: Version sim 4.30, shell 4.8 (AOD v1.1).
The 1.2 version adds "Ride of the Valkyres" & "It's a long way to Tipperary".
What do you mean the file properties do not show?
