WAPT server version 2.6.1.17787,
WinPE environment up to date (November 2025),
console on Windows Server 2022.

Hello everyone,

I have a problem (see error message in the subject line) when I try to update WinPE to the server.

Any ideas?

I'm getting the same error on my Windows 11 PC after installing the Microsoft ADK environment.

Thanks in advance,
best regards,
David

Please disregard my request; it seems the problem stems from my winpe.wim file being corrupted

Hi David,

thanks for the very quick self-resolution. :-)

I'll still submit an internal ticket to mention in the error message that the WIM file might be corrupted.
