As the title states I have been trying to install the FSD 400LS into FSX. One issue is that the installer wants to install to FS2004 and no where else and I don't have the time nor want to install FS2004 just to get one or 2 aircraft transferred over as they may not work anyway. Which brings up the next question, has somebody done this already and found it to be a waste of time? Would really appreciate help or advice on this as I have been missing having a 400ls on flight sim and am tired OOM errors from the huge MDL file on Carenado's Cheyenne III.
