I am trying to do in-place upgrades of two Windows Server 2012 R2 machines to Server 2016 RTM, with the setup tool started from Windows, and I want to keep settings and apps. Setup stops at a certain point with the following message:
Windows Server 2016 installation has failed.
Checking the error log, I can find the following:
CMountWIM::DoExecute: Failed to mount WIM file C:\$WINDOWS.~BT\Sources\SafeOS\winre.wim. Error 0x80070522[gle=0x00000522]
It is the same on both machines.
Any ideas?
