Hello,

I downloaded WinPE,
then booted my PC into PXE mode, and at a certain point, a command prompt window appeared displaying this message: "


Fying JSO with signer certificate: wapt_private_admin. Verification of
wads64.exe signature failed: ERROR: Signet wapt_private_admin (sha256 c6d0661e1216590
0a81b9a30ebbd7637c770884650506606ffd3031507b40fa) is not trusted. Reason: self-signed certificate
"wapt_private_admin" is not a trusted certificate. Aborting
X:\Windows\System32>"

. Could you please help me?
Do you also have the correct procedure for downloading WinPE? Thank you in advance.
Have a good day.
😊😊😊

Hello,

it seems that wads.exe is signed with the "wapt_private_admin" certificate, which is not included in WinPE.

Have you changed the key?

Go to the Tools menu ‣ Sign Deploy Exe.
