Hi Martynas,
I see you have posted here. Kory spotted that you installed ARM libraries instead of the x86/x64 versions which you would need for a standard PC (Intel/AMD based)
Did you have any success installing the libraries?
Today I found the problem. It was that my registry variables had drifted from C:\Windows\System32 to another location, and because of that Unreal Engine couldn’t read the .bat files — it simply couldn’t find them. Once I fixed the registry variables, everything started working, and I’m back to working on the course.
Thanks for the help! 
That is strange and that should never have happened.
At least it is working now and I’m glad you’ve got it fixed. Good luck with the course.
