Missing UEPrereqSetup_x64.exe

[sfla]

Just trying to follow the steps. I cloned the UE repo (branch 5.0, commit 6b10e3f3b7a1).
Started UBB, selected path to local repo, click "Start" and it immediately fails, saying
The system cannot find the file Engine\Extras\Redist\en-us\UEPrereqSetup_x64.exe
cmd exited with code 0
==BUILD FINISHED==
and then it still has status "Running", counting upwards, not letting me start again.
And when I try to close the application, I get options in Chinese.
I've tried the same with and without all three options (Build Setup, Generate Project Files, Build Automation Tool).


I assume I'm supposed to run a .bat-file or something, but the step-by-step README does not specify anything.

I have the same issue, but I fixed it by running setup.bat manually first

I have the same problem, but the actual issue is probably this:

Installing prerequisites...
The system cannot find the file Engine\Extras\Redist\en-us\UEPrereqSetup_x64.exe.
cmd exited with code 0`

It fails to run setup.bat because there is one "-" missing in --all parameter, so setup.bat fails to run but the program tries to continue and install things that wasn't downloaded beacuase setup.bat failed :).

EDIT: No, the problem is actually in setup.bat itself, which does not handle --all corectly.
