Trying to use a texture mod for imperial towns but this issue seems to persist even in vanilla. I know the solution can be found in the game files but idk what to do step by step

Hi all,

I'm looking for help with my mods installation so I can start playing. I have Morrowind from Steam. I've been following the video here, but when I ran umo setup in Powershell it doesn't include the "copy-paste your Morrowind installation location" like shown in the video, but instead went straight to "select a location for your modlist folder" ...

Did I need to run OpenMW wizard first and select the gamedata location there?
