Yes, the Prepar3D v1.4 sdk includes bglcomp.exe. If you have/find/buy another FSX Deluxe (or Gold), you'll need to install the sdk starting with the original and patching up to SP2 or Acceleration sdk. Definitive guide to this on FSDeveloper. The P3D sdk is a one-shot installation but doesn't support Gmax if that is important.
