Mod Organizer version history

2.5.0 Dec 27, 2021

Windows 10 1809+ or Windows 11 are now required due to the upgrade to Qt 6 and Python 3.11.

Unfortunately, MO2 cannot support Windows Store / Gamepass versions of supported games. The virtual filesystem is simply incompatible with the way the games are packaged.

For version 2.5.0, the installer will wipe any third party plugins as very few from 2.4.4 will be compatible with 2.5.0. If you've already installed a 2.5.0 beta build, I'd recommend simply overwriting the files using the archive download.

For older MO2 versions, a clean install is highly recommended if you do not use the installer as leftover files from 2.4.4 can and will break parts of 2.5.0 in addition to leaving old, extraneous files in the MO2 directory. You can migrate old portable instances by copying the mods, downloads, profiles, overwrite directories and modorganizer.ini file to the new install. If you use any third party game plugins, it is highly recommended to wait for an update before loading those instances.

Category Revamp
The default categories and Nexus category mappings are no longer hard-coded. When you create a new instance or load an older instance, you will be prompted to import and map the Nexus categories. You should be able to preserve your old categories if you had custom categories configured or use the old default mappings.

The updated category editor has a new interface to import the Nexus categories. …

2.4.4 Dec 27, 2021
  • Fixed discord invite
  • Removed Mass Effect support
  • This was really only meant for WJ support which probably won't even be happening and people got way too excited about something that doesn't really work.
2.4.3
