The solution is to remove or delete 2 folders that the UI 1.2 installer creates during the UI 1.2 installation.
The two folders are (01_ZUTI_DSMod and 01_Zuti_DSMod_v0.8_RC3.5).

The UI 1.2 Installation only creates one of those folders (the latter). Obviously you installed UI 1.2 over a UI 1.1 that was not "clean", i.e. you had additional Mods installed, or you installed another ZUTI DSMod version afterwards. A better solution would have been to disable one or both of those folders by renaming with a minus sign. You should not have two ZUTI DSMods enabled at the same time.

This is not a bug in either the UI 1.2 or the ZUTI DSMod.
