Before you say "Install x86 bit", that's the version that I installed.
I installed the launcher, and it told me to install .net core, so that's what I did. I got x64 bit on mistake because I didn't see x86 first, and figured "Oh well, should work anyway right?" Nope, so I went to the forums to see if anyone else had the same problem. They did, so I installed x86 like everyone said, version 3.1.
And it didn't change anything, I reinstalled .net core and even repaired it, it still did nothing.
The Launcher doesn't open and tells me that I need to install .net core for it to run. But it's installed.
