1. Install all parts of the mod as instructed above.
2. Open "Steam/Steamapps/Common/Medieval II Total War/mods". There you
will find all your installed Kingdoms campaigns as well as the
"Third_Age_3" modfolder.
3. Edit the name of one of the Kingdoms folders (americas, britannia,
crusades, teutonic), preferably your least favorite campaign. The new
name doesn't have to be anything specific.
4. Change the name of the "Third_Age_3" folder to the former name of the
Kingdoms folder you just edited. For example, if you edited the
"americas" folder, the "Third_Age_3" folder should be named "americas".
5. Select the appropriate campaign from the steam menu. If you renamed
the "Third_Age_3" folder to "americas", select the americas campaign. If you
named it "crusades", select the crusades campaign and so on.
6. Steam will now launch the mod.
If you have installed 3.0 or 3.1 and renamed your folders before you have installed the 3.2 Patch:
- If you have already renamed the "Third_Age_3" folder to one of your 'Kingdoms' campaigns (for example to "americas") install the patch normally.
- After the installation, move the files of the newly created "Third_Age_3" folder to the renamed folder manually.
(For example cut the content of the "text" folder from the newly created "Third_Age_3" folder and paste it into the "text" folder of your "americas" folder.)
Note : The "models_missile" folder has to be copied to the normal ".../Medieval II Total War/data" folder!
- The "Third_Age" folder can now be deleted.
