(Image is of an outdated Mod Fixer but is still usable as an example)

As an example I will be using No Inspiration Cost.

Go to the Files tab of whatever mod(s) you want to install and click on the 'Manual Download' button

1. Click on the 'File' tab or press Ctrl + M and select the mod(s) you are installing

2. Then drag the mod(s) to the left 'Active Mods' section

Once the mod(s) are in the 'Active Mods' section

3. Click on 'Save Load Order to File'

4. Finally, click on 'Export Order to Game'

Some BG3 Mod Manager issues involve the program not automatically locating the files it needs to thus failing to install correctly.

Open your BG3ModManager.exe

Locate 'Settings' at the top and select 'Open Preferences' or press Ctrl + P


In the 'General' tab of the 'Preferences' window you will see 'Game Data Path'

If installed on Steam, the path to the Data file is
E:/Program Files (x86)/Steam/steamapps/common/Baldurs Gate 3/Data

If installed on GOG, the path to the Data file is
E:\Games\Baldurs Gate 3\Data

Next, you will see the 'Game Executable Path'

If installed on Steam, the path to the executable is
E:/Program Files (x86)/Steam/steamapps/common/Baldurs Gate 3/bin/bg3.exe

If installed on GOG, the path to the executable is
E:\Games\Baldurs Gate 3\Bin\bg3.exe

Please verify that these paths are correct for your system and change the file location or drive label if necessary.

After you have verified all the pathing is correct, click on 'Save' at the bottom of preferences
Example of correct pathing and location of 'Save' button

Finally, close out of BG3ModManager entirely. Reopen and at the top of the program it should say 'Main' next to 'Campaign'. Hovering 'Menu' should show GustavDev and it's dependencies.

Shoutout to Avalonica [www.nexusmods.com] and AquaRainz [www.nexusmods.com] on figuring out the issue and making the directions. Again, thanks to Danyel for helping with the fix and of notifying me of the problem.

Fully restart your game and the mod(s) should work on the next launch.
