Did just a week ago whilst following a forum post - sadly can't find it now but found something similar - I'll lay it out here. Give it a shot: 'after installing 6.3 rename one of the original kingdom campaigns (like americas) to americas.original. And then rename ss6.3 to americas. Then install 6.4 to the renamed folder and launch the original m2tw launcher and on the drop down menu select the americas (renamed ss6.3/6.4) campaign should load.' SO if I remember right D: SteamLibrary SteamApps common Medieval II Total War mods within that directory you'll find folders for americas, SS (stainless Steel), Crusades etc.

Medieval 2 total war stainless steel unable to locate kingdoms exe. I actually just reinstalled the Stainless Steel 6.4 mod about 2 hours ago Ok i'll try with. I've recently started playing Medieval 2 again after 4 years or so and remember playing it with Stainless Steel 6. Stainless Steel 6.4. Kingdoms.exe (mind the. So recently i got M2TW and i wanted to spice it up with some mods. So i go download SS 6.4 and 6.3 and I have 6.4 instaled and i go to launch the game and it says.
Take for example, the americass folder and rename it to americasoriginal. Change the SS folder to americas. Launch Kingdoms as per usual. It'll have that Total War window pop-up. When you choose to launch game you'll further have to choose a campaign - notice they're listed same as in the mods folder - americas, crusade etc. Select americas (if you followed the above example) and it should launch SS.
