Failed Exchange 2016 CU9 Install

On my Exchange 2016, CU9 failed to install. Now MS Exchange Replication service (MSExchcangeRepl) will not stay running and MS Exchange RPC Client Access (MSExchangeRPC) will not start.

When setup (with /m:upgrade) is ran from command prompt the upgrade fails with a critical error at the end of the Mailbox Service section of the Upgrade. The setup log shows that there is an error when trying to mount mailbox database - specifically:

[2] Failed to mount database "MDB01". Error: An Active Manager operation failed. Error: The Microsoft Exchange Replication service may not be running on server Server16.McKeand.local. Specific RPC error message: Error 0x6d9 (There are no more endpoints available from the endpoint mapper) from cli_MountDatabase3 [Server: Server16.McKeand.local]

Restore from backup is not an option.

The questions are:

Will Setup /m:RecoverServer do anything to the information store?
Should I copy the .edb elsewhere before running the RecoverServer?
Is there anything else I should try before running the RecoverServer?

As the update was first ran by Windows Update (silly me), No it was not.

I will try to put it in maintenance mode.

In maintenance mode I get:

[05/12/2018 23:45:55.0320] [2] An Active Manager operation failed. Error: Invalid Active Manager configuration. Error: Active Manager hasn't completed configuration initialization. [Database: MDB01, Server: Server16.McKeand.local]

So the database won't mount.

Does the path 'C:\Program Files\Microsoft\Exchange Server\V14\Mailbox\Mailbox Database MDB01' exist? If not create it.

The path to the database is located at C:\Program Files\Microsoft\Exchange Server\V15\Mailbox\MDB01

I'll create the path and report back.

Back to the orginal error message.

When MSExchangeRepl service tries to start I get a message in the event log:

Watson report about to be sent for process id: 10496, with parameters: E12, c-RTL-AMD64, 15.01.1466.003, msexchangerepl, M.E.Cluster.Replay, M.E.C.A.AmHelper.HandleKnownExceptions, S.IO.FileNotFoundException, 7374-dumptidset, 15.01.1466.003.
ErrorReportingEnabled: True

I think I am done for this evening.

I was able to get the services running and allow the update to complete successfully. The contributors did give me some hints on how to get the update to run, but most of the leg work was mine.
