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.

Bug Workaround

First workaround found by marvinpunz:
  1. Press Ctrl + Alt + Delete
  2. Choose Task Manager
  3. Right-click on The Sims 4 Mod Manager
  4. Click Expand
  5. Right-click the newly expanded item
  6. Click Bring to front
  7. Click Maximize

Second workaround found by sim508:
  1. Make sure The Sims 4 Mod Manager is closed
  2. Go to %USERPROFILE%\Documents\TS4 Mod Manager
  3. Open the file config.ini
  4. Change location to match the following:
    location = 0, 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.

I had to leave a comment, first of all, on the well thought out page, and the ample amount of information available, if one takes the time to read it. Second on the easy and effectiveness of the program. It has been immense help with TS4. I recently ran into a problem and as a result reinstalling the program again, step by step to find where problem occurred. While doing this all of a sudden TS4 Mod Manager would not open, I came back to your site and found the fix right away with the config 0,0 setting. Thanks for making my chore that much lighter. Keep up the excellent work.. DocD

Default Config file
I have been having an issue getting the mod manager to open. I tried to follow the work arounds but neither worked. Upon trying the second I noticed the my config file has literally nothing in. Its just a blank text doc. I feel like that is not how it should look. I have also uninstalled and reinstalled and still having the issue. I am at a loss for what else to do.

Well, I am using the mod manager as of now everything updated and all works except for some scripts it gives me an error. And do enjoy the ease of use and compatibility of this mod. Just now I do not believe all my content will be available in game and don't necessarily know whats going on.

Hello, I just installed this and want to use it to auto-update all my mods. It says "cannot connect to internet" though my internet is working fine. Is there a way to troubleshoot this error?

Things like this are a must when installing mods/custom content for any games.

#489 Old 30th Apr 2018 at 10:19 AM
I doubt this will work anymore.

Today a .zip file can contain both .package and .ts4script files in one .zip, .rar or .7z archive. Only very old mods use .zip for script files. The "standard" is .ts4script.
It is very easy to install mods without tools like this.

By the way my antivirus program report the support page as dangerous.

This mod manager does not work for me, it loads up, but then it just shuts itself back down. So I'm not sure what is happening, and what I need to do, but it doesn't give me enough time to try the work around.

Default Deleted Sub-folders
When I go to move a mod to a different folder folders that I have deleted are still showing on the "Move To" list. How do I delete them?
