Tes4Mod:Better Cities/Mod Organizer 2 Install
https://www.nexusmods.com/skyrimspecialedition/mods/6194 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.
If you want more information about what a specific ESP in the BC archive does, then read What Does Each File Do.
If updating from an older version, please ensure that you uninstall the old version before installing the new version.
In Mod Organizer 2, click the button "Install a new mod from an archive".
Answer each query.
Once Better Cities is listed as a mod in Mod Organizer 2, place a tick to activate it.
If there is a Better Cities Update archive then repeat the above for this archive too.
Adjust your load order so that all Better Cities ESPs are near the end of your load order. All Replacer ESPs should be BEFORE the Better Cities ESPs. All Better Cities Patches should be AFTER the Better Cities ESPs, starting with the FPS patches, then the compatibility patches. Highly recommend using BOSS (Better Oblivion Sorting Software) for this.
