When installing CU23 update on Exchange 2016 Standard from CU19, I am getting the error shown below. This completely corrupts Exchange and I have no choice but to recover from a backup. I have tried turning off our AV product completely and re-running the install, same issue. I tried killing all processes in task manager that were safe to kill and running it again, still no luck.
I am at a complete loss on how to get this update installed and know the pain I face when I next try this again. I was offline for many hours last time and when I restore the server all the services return inactive and need to be manually activated again.
The fault appears to occur on the Installing Language Files step and I receive the following error: An unexpected error occurred and a Watson dump is being generated: The process cannot access the file 'C:\ProgramFiles\Microsoft\Exchange Server\V15\Logging\lodctr_backups\InstalledPerfCategories.log' because it is being used by another process.
Has anyone else experienced this problem and does anyone know what I need to do to get past this point safely please?

2023-01-03T16:55:34.08+00:00 Thank you for your reply. I did actually rename this file when the issue occurred on one install attempt. This really was me checking whether a process was holding onto the file. The rename did work, so I re-ran the installation at that point and it created the file again and still failed with the same error on the newly generated file!

Welcome to the Microsoft Q&A platform!
In order to better solve the problem, would you help collect the following information:
- How did you install CU 23?
- Whether there is any error id in the Application log?
Besides, I noticed that you said that the error occurs on the Installing Language Files step and turned off AV.
Did you disable Defender?Set-MpPreference -DisableRealtimeMonitoring $true -

1) I ran the installer using the following command on the first couple of attempts. Then later restored and re-ran using the GUI - all elevated to run as Administrator. The command: Setup.exe /m:upgrade /IAcceptExchangeServerLicenseTerms DiagnosticDataON.
I did run all the pre-requisites prior to running the upgrade.2) I did look at the install log when this occurred, but there was no error ID or messages prior to the message reported in the GUI. The services were attempted to be restarted and the transport service did error afterwards, but I didn't note that event ID as I got to the point where I just rolled back (restored) the server instead.
I did not disable Defender. This could be worth a try, thank you for the suggestion.

I am glad to receive your reply. If you have any further updates on this issue, please feel free to post back.
By the way, we need to disable any antivirus and any backup software in the update. You could check the detailed steps of this article: install-exchange-cumulative-update

2023-01-10T10:18:33.04+00:00 Thank you for your question. I am afraid I have not yet had the chance to attempt this again. This is for two reasons, the first is that this is a production server and finding a window of opportinity if difficult, and secondly, I am aprehensive about risking it again to be honest! I will update this when I undertake the update.
