Got a message saying setup failed because I already have the Visual C++ stuff installed (which I do, can see it on my programs list in control panel) so I really don't know, checked .NET framework stuff too since I know that can cause issues sometimes as well but all's good with that too
EDIT: Saw there was a new version of the game, downloaded that and the audio works!!!
Firstly don't apologise I feel like an ass constantly being like "um it still doesn't work" T_T
That being said, ran the UE setup and it detected I needed ANOTHER different .NET Framework so I installed that and somehow it STILL doesn't work, starting to think I just have a cursed version of Windows 11
