I as well have been spending the past few days trying to figure out how to install FCOM. If we use the method described by the OP, do we disregard http://devnull.sweetdanger.net/fcominstall.html set of instructions completely? Specifically, do we still need to download each mod (OOO, MMM, FRANS, WarCry, Bobs armory) separately, and then create the FCOM OMOD? Or does downloading the files mentioned in the OP include all the necessary mods for FCOM?
No, the installation procedures at post 1 in this thread is for MMM and FCOM only. For all other components like OOO, Frans, etc., the description still applies. What you should disregard is the "Martigen's Monster Mod" sub-section and the "FCOM Add-Ons & Other Supported Mods" main section. You should also ignore the "FCOM Expanded Load Order" description and use BOSS instead. And finally, in the "Bashed Patch" section, disregard bullet steps 2 & 3 under "New Game" or steps 5 & 6 under "Saved Game" (since those steps are now handled automatically by WB). I think that's it.
And, another advice - when installing Frans, make sure
not to answer yes to use Living Economy (same is true when installing OOO, but LE is installed as separate file(s) from OOO and thus easier to remove later). Instead, use my Enhanced Economy mod, which is more compatible with FCOM (and other mods) than Living Economy is.
