You can install FL on an another PC, activate whatever mod you need there, then move the whole FL folder to your main PC. (FL can usually function without a proper installation. I have several mods on my PC that way beside CF - two russian SP mods and couple of Discovery versions)Alternatively you can make FLMM to change the Freelancer directory it works with.Also don't forget to change MyGames/Freelancer folder (I have one for each mod I have).
