You download the mod, and if it has an installer, you direct the install path to wherever you installed M2TW, let it install, and when it is finished you load it the same way you run M2TW (It overwrites the old game).

Or if it comes as a folder with a different version of the Data folder, you just take everything in the folder and paste it over your Vanilia files...
Not the same anymore

You must have the files unpacked, and use a BAT file to launch the game.

Omanes will be here shortly, I presume, to help you out.

Good day.
