Build failed, unknown error

Hi, I realized my game was unable to launch, so I am trying to fix this before I build anything in case I need to reinstall or something. Here is a screenshot of my error. Someone please help, I’m new to game-making and coding so I am not very good at figuring this stuff out. I’ve used the engine before but never had this problem.

Next time attach the actual output log please. Makes it easier to read/search.

But, it is probably because your install paths are messed up. Manually install the Unreal Launcher and Engine on the same . Your issue seems similar to [this.][1]

Thanks! It is downloading as x86 instead of x64, I’ll try to find another download for it
Not sure what to do though, I can’t find any other download.

Yeah, because they wanted to make it available for non-64bit OSes too.

I re-downloaded it and it still isn’t working. I couldn’t find any other version than the x86, I have no clue what to do. It’s hitting the same errors as in the picture before, and I also googled this problem for over an hour and found nothing. Do you have any other ideas?

Yup, not one you’re going to like though;0 Uninstall UE4 and reinstall.
