Hello,

I am trying add and upgrade Win 1903, but it always failes with the error below.

Error:
 "Remarks from the CreateProcess is Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source."

I have tryed re-downloading the Windows 10 iso from diffrent sources but get the same result.
Updating PC that has "Windows 10 Professional Edition (x64) - v1809"

Following this guide:

We have Desktop Central version 10.0.400, and before that we had version 10.0.388, same issue on both versions of Desktop Central.
