WinNTSetup "Windows setup files are corrupted" error. How to fix?

Question

Windows

Good day! I am installing Windows 8.1 on a tablet. I cut it into a WinPE flash drive from xemom1, boot up, open WinNTSetup, press any button and get the error "Windows installation files are corrupted":

It used to work, now it's probably something with the flash drive, but everything works fine, except for this program, but it's the one you need , because it allows you to choose where to put the bootloader and system edition (and does not ask for a key :)).
I tried to download from the Internet and run it by booting into WinPE, but everything is the same. Has anyone encountered this?
Ps I still use a phone with DriveDroid as an additional flash drive, it contains an image with Windows and downloaded WinNTSetup on it, but I can’t cut WinPE onto it, because the system doesn’t see it when it boots up, and I can’t boot from it.

The question can be considered closed. I couldn't solve the problem and still used 78Setup.
