cant get tacview to work in falcon bms 4.32 (tacview 1.2.4)(win7 64-bit) what can be wrong ?

You don't need to run tacview whilst in BMS, it is able to open the ACMI files recorded from in the game.

Press "F" in game to start the recording and same again to stop, then navigate to Falcon BMS/User/Acmi

files are stored there and Tacview can read them, just i have found you have to set the terrain in tacview to the correct falcon terrain.

Hope this helps
