I re-installed FSX again about 10 days ago having bought a copy of the Acceleration Pack. It was on my PC for about 4 days before I once again decided to remove FSX as it just does not float my boat.

Coincidentally, I was in the process of creating a fictitious airfield in FS2004 using EZ-Scenery. I was about 50% of the way into this project when FSX was installed and removed. Prior to FSX installation, I had a couple of AI Sea Kings flying circuits (successfully) around this airfield. After FSX was removed, I noticed that the AI helicopters would not land, rather they would take off, fly the circuit, turn base leg then slowly fly into the ground without turning onto finals.

At first I thought that my AFCAD was at fault but I checked and double checked and could find nothing wrong. I then went to my other airfields which are populated with helicopter traffic and noticed exactly the same anomaly with every AI helicopter on my system – they just will not land.

I then changed the flight plans from VFR to IFR but with similar results.

Finally, I downloaded a fresh copy of Elvis S76 for AI but still it would not land.

Would anyone know if installation/removal of FSX has any effect on any aspect of FS2004?
