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.

  3. Open the file config.ini
  4. Change location to match the following:
    location = 0, 
  5. Save and try opening The Sims 4 Mod Manager again

Third workaround found by rpastorcale:
  1. Hover over the icon for The Sims 4 Mod Manager
  2. Wait for the preview to show
  3. Right-click on the preview and click Maximize

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.

Incredibly cool. Thank you @Raxdiam

Works right out of the box in Windows 10. Essential piece of software for any mod shopper. :up: :D :Pint:

With the number of mods and CC I have I probably couldn't function without this (last count 363 active out of 479), especially with different versions of mods and add-ons that mod creators include with their mods, it's nice to be able to click and choose and makes tracking outdated mods that are causing errors easier.
Unfortunately I've noticed the Mod Manager is not supporting ts4script files. When I've tried to add a script mod, only the package files are loaded, I still have to manually add all my script mods and then still only the .package files show in Mod Manager. It's not a huge issue since I don't have nearly as many script mods as package mods, but the description indicated it also supported .ts4script files and I wanted to make sure it wasn't an error or if there's some setting I need to change in order to see and load .ts4script files with the manager.

This is unusable for non-english speakers. The save and mods folder is called "Les Sims" in french for instance whereas the mod manager is looking for a folder called "The Sims" and won't let us change it in the settings. What a shame!

I have a shopping problem. After I acquire items, I'd like to look at each one and be able to remove or keep it in an organized fashion. I can't figure out how to get this tool to let me see the objects/sims/build mode/etc. Am I using this incorrectly? Is that beyond the ability of the tool?

Please advise.

It sounds like it's beyond the ability of the tool itself. Unfortunately it seems the mod-creator is retired, so the tool hasn't been updated in a while and no longer supports script mods, but if you're referring to the ability to "see" CC items and add/remove them after making sure what they are (like if the package has an unclear title and you can't remember what it is) while there's no easy way to do this, you could try installing S4PE so that you can open the package file and check the IMG resources. Some CC is nice and includes a thumbnail in the .package file, but otherwise, while the IMG file just shows the textures in an unfolded setup, checking them can help you figure out what the item is and you can just delete it from your Mods folder.

Go to "Documents\TS4 Mod Manager\config" and change "The Sims" to "Les Sims"
and change "autoupdate = true" to "autoupdate = false"
launch the mods manager, problem solved.

you're welcome...

Thank You so much for this Mod Manager. I have always used this one since it first came out and love it. I have even tried other Mod Managers and this one provides the functionality I enjoy. I like that I can add or remove my mods simply by scrolling down the list and ticking or unticking the box next to the mod. Also love that I can create a sub-folder for each item type, such as one for Build Mode items and CAS Items.

Same problem as darkfae3. Definately needs an update.
Would also be cool (but admittedly difficult, I am a fellow programmer) to grab and download mods should one provide the URL from modthesim as well as checking against the version availible upon start.

Raxdiam, thanks for giving it a shot. I guess I'm spoiled by Mod Manager for Fallout, Skyrim and other Bethesda games. This mod manager is basically a mod listing program, not a manager. For example, unless I'm missing something, this MM does not recursively search sub-folders even though the game allows users to install mods several folders deep. I could go on, like not warning of conflicts. And so on. But, I'm a programmer myself and can appreciate the effort to create a mod listing program.

I understand that this MM is no longer working properly? I noticed that the ts4scripts are not loading as needed.
Let's say it all together: Goodbye!
