Ok, so I decided to buy Unreal Tournament GOTY from GoG the other day because I had always wondered what it had over the non-GOTY version, and so far it works pretty well (and I like all the extra skins and stuff! 😁), but I can't seem to figure out how to install umods on it.

Everyone just says "LOOOL just double click the file and it'll install!" or "you have to associate the extension with setup.exe in the game's system folder", so I tried that but whenever I go to click on a umod file, it gives me this error:

1Critical Error
2Setup: Unknown Disposition
3History: UsetupDefinition::Init <- WFilerWizard::WFilerWizard <- Setup

Is there some other way of installing umods? I really really want to try ChaosUT (they left it out of the GoG release for some dumb reason, but it can easily be found on ModDB) 🤣
