I'm fairly sure, just point the installer at the swkotor folder and hit go, right? I made sure to point it there, not at the override folder. And yes, the game is in English.
I can record and upload my install and crash to YT if you think that would be helpful so you can see what's going on?
I currently have to leave a 1* review as the game crashed when I clicked on the robes item in my equipment screen. I will of course revise my review should the mod be updated!
Edit: The author updated the mod and it works perfectly now!
I tried to run this mod and after adding the item and clicking on it (not equipping it, just clicking on it so you can read the item description) the game crashed. This was on a completely clean install, no other mods installed, no k1 restoration, no cracked executable or uniws modifcation.
