We are at Exchange 2016 CU 10 and trying to go to Exchange 2016 CU 13, it keeps coming back with the following error:

Error:

Could not find a part of the path 'C:\Windows\Temp\ExchangeSetup\bin\EnterpriseServiceEndpointsConfig.xml'.

 

Warning:

An unexpected error has occurred and a Watson dump is being generated: Could not find a part of the path 'C:\Windows\Temp\ExchangeSetup\bin\EnterpriseServiceEndpointsConfig.xml'.

 

I have tried all previous known workarounds and nothing is helping

Check the following leafs in registry HKLM\SOFTWARE\Microsoft\ExchangeServer\v15: AdminTools,
ClientAccessRole, FrontEndTransportRole, EdgeTransportRole (when applicable), HubTransportRole, MailboxRole, and make sure keys ConfiguredVersion/UnpackedVersion/PostSetupVersion match. Add missing or adjust according to installed Exchange version (you can peek at HKLM\Software\Microsoft\ExchangeServer\v15\Setup\OwaVersion). After that, give setup another try.

Tried that already and that didn't work. Do you have any other suggestions?
