With the 1.29 Manchu Update we are upgrading EU4 to the Paradox Launcher! This new launcher will give us a great baseline which we will build on to add lots of new features to enrich your EU4 experience.

eu4_new_launcher.png


This new launcher will change how EU4 works with Mods - for example you are now able to disable or enable all mods with a click of a single button! The new launcher requires that you do one thing to transition from the old way mods work into the new system.

If the mods in your launcher looks like this:
mods in new launcher.png

Then all you need to do is navigate to "...\Documents\Paradox Interactive\Europa Universalis IV" and delete the folder called ‘mod’. (Make sure you backup this as there might be stuff you want to keep in there)

Steam should then reacquire your subbed mods in the new format and you are good to go just as you were before - but with a shiny new launcher!

If you are a modder yourself
There are some things you need to do to keep your mod working / create new mods going forwards. Please go here for more information!

Further Troubleshooting:

If you have problems with steam re-downloading your mods you should try the following:
  1. Check if there is a steam workshop content download for Eu4 pending - if there is then start the download.
  2. Restart steam - this often works!
  3. Restart your PC - the good old off and on again fix works more than you might think...
If none of the above works then you can try:
  1. Go to steam and unsubscribe to the mod that isn’t being reacquired.
  2. Resubscribe to the mod - steam should then reacquire it.
If after trying all of the above you still can’t get mods to work then please submit a ticket here: support.paradoxplaza.com or visit our Technical Support Forum

If you are downloading your mods from the forum rather than through steam then the old method of copying the mod directly into the "...\Documents\Paradox Interactive\Europa Universalis IV\mod" will still work as before.


If the launcher fails to start or you cannot use it for any other reason, you can always run the game directly.

To do this, right-click on "Europa Universalid IV" in your Steam library, go to "Properties", switch to the "LOCAL FILES" tab and click "BROWSE LOCAL FILES...". This will take you to the folder where EUIV is installed. Double click "eu4.exe" (Windows), "eu4" (Linux) or "eu4.app" (macOS) and the game will start without using the launcher.
The default settings enable all DLCs you own. If you want to disable specific DLCs or enable Mods without using the launcher you will have to edit the file "dlc_load.json", usually located in "C:\Users\your_username\Documents\Paradox Interactive\Europa Universalis IV" (Windows), "~/.local/share/Paradox Interactive/Europa Universalis IV" (Linux) or "~/Documents/Paradox Interactive/Europa Universalis IV" (macOS).
To disable DLCs, add them to the "disabled_dlcs" list, to enable mods add them to the "enabled_mods" list.

"dlc_load.json" Example:
{
"disabled_dlcs":["dlc/dlc065_fredmans_midsummer_epistles/dlc065.dlc","dlc/dlc052_sabaton_soundtrack/dlc052.dlc"],
"enabled_mods":["mod/ugc_1792575623.mod"]
}

[UPDATE: 09/18/19]

Instructions for Modders

Current mods will keep working with 1.29 (As long as they are not broken by in game changes we made). No action is required until the mod is updated. Mods uploaded with the new launcher will show up in the 1.28 launcher but will not work (Clicking on them has no effect).

Creating mods
- Open the launcher
- Got to "Mods"
- Click on "MOD TOOLS"
- Fill in all details (Note that "Version" specifies the mod version not "supported_version", that needs to be put into the descriptor manually)
- Click "CREATE MOD"
- The launcher will create the folder and two descriptors: "ModName.mod" in "mod/" and "descriptor.mod" inside the mod folder. "ModName.mod" is local only and will not be uploaded. What will be uploaded is "descriptor.mod" and any files inside the created folder. This is also what will be downloaded when subscribing (Plus the launcher-created descriptor, see "Good to know")
- This means that "ModName.mod" is just for convenience, anything that should end up at subscribers should be put into "descriptor.mod", that includes "supported_version", "tags", etc.


Uploading mods
- Open the launcher
- Got to "Mods"
- Click on "MOD TOOLS"
- Go to "Upload a mod" tab
- Select the mod you want to upload. All mods will be shown here, uploading any other than your own will fail with a credential error.
- Select "Steam Workshop" below "Upload to", "Paradox Mods" currently does not work for EUIV
- Enter a description and upload
- Set the mod public in its Steam Workshop page


Updating mods (improved version updated 20190926)
Currently most mods have one mod descriptor, usually ModName.mod. This is now split in two: ModName.mod which has the name entry and a path or archive entry only and descriptor.mod inside the mod folder, which has everything else. Updating them means creating this descriptor.mod and moving most things from ModName.mod into that. So essentially: Keep name and path or archive in your current .mod and move everything else into descriptor.mod inside the mod folder.
-If you have an issue with creating the descriptor file you should note that you can simply copy the content of the .mod file into the descriptor - this should not cause an issue.
-Remember that the descriptor.mod file should be inside the mod folder.
-If you get a credential error when attempting to upload a mod make sure you have something in the description section - you can simply put your current description from the workshop here. If your workshop description is to long for this then update the mod with anything in the description box and then add your full description later.
-Remember to select "Steam Workshop" in the "Upload a mod" tab, since "Paradox Mods" is not currently supported.

Good to know:
Currently mod zips show up in "C:/Users/user/Paradox Interactive/Europa Universalis IV/mod" after subscribing. This works slightly different now. Mod zips (Now named *.bin) will now stay in the Steam downloads folder (Something like "D:\SteamLibrary\steamapps\workshop\content\236850\217416366", but users should not have to care about this, it is handled by Steam exclusively and shouldn't be touched) and the "mod" folder will just contain "ugc_1234567.mod" files ("descriptors") that reference these downloaded files. The old way of copying mods into that folder will still work however.

If you have questions or want to discuss these changes with the modding community, please do so in the Modding subform here!

Will the new launcher be only applied to 1.29 and onwards or the change will also retroaffect the older versions?From what i understand,it's only 1.29 and onwards but i just want to be sure.
Thanks for any replies about this.

That's nice. Maybe you could do similar for HOI4 and CK2. That mod screen in launcher is very practical.

HoI4, yes. CK2 no I'm afraid. More info on HoI4 later on.

Will mods that are currently fully compatible with 1.28 and the old launcher need to be reuploaded to Steam, or will there be an option to simply update them to be compatible with 1.29?

Does the launcher actually work on Linux this time around? It's been broken since launch for Imperator despite multiple bug reports and posts in the corresponding technical support subforum.

Does the "--skiplauncher" command work when launching the game?
"--skiplauncher" no longer exists, but starting the game directly without arguments will have the same effect since the launcher is now a separate executable.

Will mods that are currently fully compatible with 1.28 and the old launcher need to be reuploaded to Steam, or will there be an option to simply update them to be compatible with 1.29?
If you want to change "supported_version" you need to reupload in the new format, if "supported_version" is not set there is no update necessary, it will just work.

Local mods will work just like before.

I gather the effective changes are exclusively uploading and downloading from the Workshop, right?

Thanks for the reply, though think it should be more clear that this is largely workshop-related.

I would note that, if you have local mods in your mod directory, do NOT just delete the directory unless you've made a backup first... ;-)
