Some questions for you:
Did you try an upgrade of Windows 10 1607 -> 1703?
Did you do a fresh install of the Agent, or did you try an upgrade of a currently installed Agent?
Both tried it. Removed MA 188.8.131.528 and installed again.
Removed again MA 184.108.40.2068 and installed 220.127.116.119.
Still same error.
Yes it is an upgrade from Windows 10 1607 to 1703
So, I am assuming, that you are still trying to upgrade to Windows 10 1703, right?
If that is the case, I would advise to completely uninstall every McAfee software (ENS 10.5 and Agent 5.x). I have read some cases, where the upgrade is not working because it is not detecting the products correctly. Even appraiser updates do not fix that issue.
What you can also do is to manually create a Windows 10 1703 installation media and force the upgrade over that media (in case you did not do that already).
Keep in mind that MA Agent 18.104.22.1689 has been pulled due to some buffer overflows. I would advise you stick with the MA 5.0.5 RTW version.
Thank you Alex, will try that.
Does it work?
Can you successfully do in-place upgrades of Windows 10 to 1703 Creators Update while McAfee agent 5.0.5 is installed?
I'm trying to upgrade and it's failing even though I have all the required versions and patch level for 1703 listed in the link below:
