  1. I installed the Quadrology on 2 computers, both clean installs of Win7 Ultimate, at the same time. Computer 1, everything installed completely. Computer 2, Everything installed EXCEPT the two clan packs for MW4. I’ve tried reinstalling twice, but the clan mechs do not appear for computer 2.

  2. it works on windows 10 with r7600x+6700xt. You just need to add /gosNoJoystick at the end of the shortcut. should look like this. Have fun lads, unlike myabandonware MW4 and MechCommander 2 here all works.

    “C:\Games\MechWarrior 4 Mercenaries\MW4Mercs.exe” /gosNoJoystick

  3. i am getting really long startup times for this game (installed from Mech warrior quadrology, though i did not get mechwarrior’s 1,2, and 3.) on windows 7, would anyone know how to make it faster by chance?
