The Mod Enabler is what Herr Propwasche requires for his DM mods (as explained in the 3rd party mods section of this forum):
"HPWDM2.2\aircraft folder with 477 individual aircraft folders and .xdp files
readme.txt
INSTALLATION: Important! This version of the damage mod is intended to be used only in conjunction with Jonesoft's Generic Mod Enabler and should not be installed UNLESS JSGME has already been installed into your CFSWW1 Over Flanders Fields game folder. With JSGME, installation and use of this, or any mod, is very easy. Simply extract the contents of the HPWDM2.2 zip file into the MODS folder which is created when you install JSGME into OFF. The mod is correctly installed if you see the readme.txt and the following folder structure inside the MODS folder: HPWDM2.2\aircraft\Alb_DIII_AC1, etc. To load the mod, simply run JSGME, highlight the mod you wish to use, click on the top button, and then start your game. That's it!
NOTE: This mod may be used in QC battles AND the main campaign"
