When firing a missile against an airliner, I can shoot it down but I do not see any effect of the explosion on contact with the missile. I think I had the same problem. Try to run FSX as "Administrator" Johan

Many thanks to Johan. Running FSX as Administrator the problem is solved. "Weapon for FSX"is fun, the price is low and we hope it to run in multiplayer in the near future
