Receiving the following install error for Exchange 2019 cumulative update 11

Step 6 of 10: Mailbox role: Mailbox service
Error
The following error was generated when "$error.clear():
start-setupservice -servicename msexchangedagmgmt
was run - service 'Msexchangedagmgmt" is disabled on this server - system.invalidoperationexception: Cannot start service msedchangedagmgmt on this computer
The service cannot be started, either because it is disabled or because it has not enabled devices associated with it.

I have set the service to automatic and restarted with no resolution.

    @Jason Stevens

    Try to run update with administrator rights.

    If the update still fails, you can manually start the service after the installation starts and before step 6.

    You can also use administrator rights to run a script to monitor and start this service during installation(Run this script before installation, stop it after installation):

    While (1 -le 2){Sleep 1; Get-Service | Where { $_.DisplayName -eq 'Microsoft Exchange DAG Management'} | Set-Service –StartupType 'Automatic'}

    Microsoft have documented this here: https://support.microsoft.com/en-us/help/4487563/description-of-the-security-update-for-microsoft-exchange-server

    Run the install as Admin is the resolution.

    Hello JasonStevens,

    Seems like a known issue of this Cumulative Update.
