Adding Mods

With previous versions, installing package mods required you to first extract the ".package" files somewhere, and then add them with the manager.
In the current version of TS4MM, that step is removed. If the package mod or mods that you have downloaded are contained in a ".zip", ".rar", or ".7z" archive, you can simply drag them in to the manager, or add them with the button, and the manager will automatically extract any ".package" files in the archive into your Mods folder.

You do not have to worry about whether or not the mod you download is a script mod. The manager will discern the difference by looking at the contents of the archive, and if it is a script mod, it will copy it to your Mods folder.


Applies only to the mod manager tab.
Ctrl + AAdd mod(s)
DeleteRemove selected mod(s)
Ctrl + RRefresh mod list
Ctrl + EEnable selected mod(s)
Ctrl + DDisable selected mod(s)
Ctrl + Shift + RRename mod
Ctrl + Shift + ASelect all mods

Unzip and extract anywhere, then double-click "TS4MM_<version>-Setup.exe" and follow the steps for installation. After it's installed, simply double-click the icon on your desktop named "TS4 Mod Manager".

Requires .NET Framework 4 or higher.

To prevent this bug

The best way to prevent this bug from happening is to not close TS4MM while it is minimized.
This bug happens because I made it so that the location of the window on your screen would be saved to a configuration file, so that when you open TS4MM again, it would be in the same place you last opened it.
What I should have done in the first place, is make it so that it would not save it's location while minimized.
I apologize for my mistake. This will be fixed in the next update.
