Tes4Mod:Better Cities/BAIN Install
BAIN is an automated mod installer which is part of Wrye Bash. Use the Wizard install for easier process (right click on the archive and select Wizard).
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.
Simply place the downloaded archive into the "Oblivion Mods\Bash Installers\" folder, then go to the Installers tab in Wrye Bash, run the Wizard on the archive and answer each query.
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.
