Seriously what the shit is this? I got the pre-alpha ages ago when it came out and just recently downloaded a massive patch and now i'm getting this. It used to play just fine
If I had to guess, I'd say the procedure entry point ?GetLinker@FArchive@@UEAAPEAVULinker@@XZcould not be located in the dynamic link library UE4-Core-Win64-Test.dll.
It's something missing in the dll (the libraries that the linker connects with the other code files), so the dll must be bad. Just uninstall, delete everything, and start from scratch.
I'd try to find a new version of UE4-Core-Win64-Test.dll first, and replace your old one. Maybe that dll was patched in some earlier version and isn't included in the latest update.
