I'm a new user of FS2004 and, unfortunately, not even close to being a computer expert. I tried to download an aircraft by saving it in the 'Flight Simulator Files', then ran FS2004 and expected the new aircraft to show up in the list under the 'Create a Flight' menu, but it wasn't there.
Can anyone give me any help on how to download properly, what folder/file to save to and anything else I should be doing to be able to use a new downloaded aircraft.
Follow either one of these instructions and you should be home free.
If you have a problem please ask.
