OK.

Find your MTW VI folder.

It must be named Medieval - Total War if you didn't change the name manually.




Next go inside if there is another folder named 'Medieval - Total War' - if yes there is a problem you can deal with EASILY.


If there is such internal 'Medieval - Total War' folder go inside you will see numerous folders and files - select all files and cut them.

Next leave this inside 'Medieval - Total War' returning to the original Medieval - Total War folder and paste the files and folders you have just cut.

You should replace the vanilla files this way and the mod MUST work fine now.






If you cannot find anything called Medieval - Total War inside your Medieval - Total War foder I suggest to uninstall the game, reinstall it and the Viking Invasion and now install PMTW 1.5 to the directory where is your MTW folder and do the same with the main file of the PMTW patch.

You will easily notice when it is all right - PMTW removes the video intro to the game and the load screen/menu background is different.
