Q-400 not showing up in aircraft (plus out of installs) FSX
So 4 years ago I bought the q-400 pilot edition. today I have become interested in flight sims again and I was able to get the key/install.
But after i install it it doesn't show up in the aircraft selection. it said "this installation package could not be opened"
i have tried to install it again e.g running in administrator. i was about to try to install it without the antivirus but i have run out of installs.
