You can delete the third_age_3 folder altogether and reinstall using the zip files we provide. Start with third age 3.2:
1. Download the file below
Third_Age_3.7zip N.B. file size is 3.29 GB
2. Unzip the file in the 'mods' folder of your Kingdoms install. The result should be a folder named 'Third_Age_3' located in the Kingdoms 'mods' folder.
3. Optional, check if a TATW campaign can be started.
And then install DCI: Last Alliance:
1. Download the file below
DCI: Last Alliance Public Beta 7zip Download | Mirror #1 | Mirror #2|
2. Extract/unzip the downloaded DCI_LA_BETA.7z file into your '...\Medieval II Total War\mods\Third_Age_3' folder. Accept overwrite and/or merge folders when requested.
This process will overwrite your TATW files, meaning that you will not be able to play TATW.
3. Run DcilaCleaner.bat - located in '...\Medieval II Total War\mods\Third_Age_3' folder This is absolutely necessary.
4. Run CreateLauncher.bat - located in '...\Medieval II Total War\mods\Third_Age_3\dcilaOtherFiles' folder.This creates a shortcut on your desktop, creates DCILA.bat and DCILA_NoBaiSwitcher.bat, and deletes Third_Age.bat.
5. Launch the mod by double clicking the 'DCI Last Alliance' icon on your desktop or the DCILA.bat file (DCILA_NoBaiSwitcher.bat will run DCI:LA without the battle AI switcher)
Optional: delete the Third Age Total War shortcut from your desktop
