Exchange 2016 update from CU4 to CU8. Error: Could not find a part of the path 'C:\Windows\Temp\ExchangeSetup\bin\EnterpriseServiceEndpointsConfig.xml'.

Question

Greetings,

I'm going to start the CU8 update on a Exchange 2016 CU4 server. When i launch the setup process, it informs me that the previous update did not complete. At the first step of the update process, i get this 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 checked the Windows Temp folder and i didn't find the file requeted, but i found it on my Exchange installation folder. The Enviromental variabel TEMP is correctly configured and the system is fully patched with the antivirus software temporanly deactivated.

How could I get it work?

Thanks for your help.

Problem Solved:

Relaunching the CU4 installation package, the process tries to fix missing components. The installation of the CU8 starts correctly now.
