📋 About This Mod

Mod Organizer (MO) is a tool for managing mod collections of arbitrary size. It is specifically designed for people who like to experiment with mods and thus need an easy and reliable way to install and uninstall them.

Mod Organizer 2 is a mod manager created by Tannin to support 64bit games like Skyrim Special Edition and Fallout 4 in addition to all the 32bit games MO1 already supported.

Tannin discontinued the project when he was hired by the Nexus team to develop their new Vortex mod manager.

MO2 was not completed and was left with many issues. LePresidente managed to fix it to a usable state by himself after SkyrimSE came out, adding support for it, and releasing v2. 0. 8.

The project took up speed again after a few more coders showed up in late 2017, and an incredible amount of work has been done!

Credits to Tannin, LePresidente, Silarn, erasmux, AL12, LostDragonist, isa, AnyOldName3, Holt59 and many others for the development.

A Special Thanks to all the testers of the discord server and everyone else involved for supporting the project!

Mod organizer 1 Legacy (thanks enpinion):

Recently Nexus changed their services to be compliant to the new EU rules. These changes required programs making use of them (such as MO1, NMM and MO2) to be updated to be able to still use Nexus integrations.

Even though MO1 is End of Life and will not get any future updates, enpinion managed to get the Mo1 code to build and has been able to fix this issue. We discussed with Tannin (original creator of MO1 and Mo2) and decided to host here the fixed Legacy version. This does not mean that Mo1 will receive any further updates, or that it is supported in any way. The Mo2 team will continue to work on Mo2 and strive to make it the better program.
