MikeyD's mods are a pain to install BUT why would you ever uninstall them? Instead of using McMMM unzip the first set of bmps into a folder. When windows asks do you want to overwrite say no one at a time. DO NOT say no to all.
Alt bmps and the other folder bmps need to go into their own folders. Use view, thumbnails, to see the bmps in the folder and right click, open with, to view full size.
To delete a mod in McMMM, uninstall the mod if installed, go to uninstalled menu, click the mod, then in the top tool bar click edit mod and delete mod in the dropdown.
