I keep my servers fully patched and installed all CU's, SU's and HU's to date, but I am strangely getting this error for the latest Hotfix, I've done all my usual steps of disabling AV and running the EXE from elevated CMD prompt and using my Domain admin account, but can't get past this, any suggestions please
Thanks
Had the same experience on a few servers. In all cases the retry worked.
Had the same issue on a Windows 2019 Server with Exchange 2019 CU15. Retry did not work for us. The same dialog appeared again. We decided to cancel it and skip the update for now. That did not work. After that all exchange service was in a disabled state. We tried to rereun the update and then it completed sucessfully. But still all services was in a disabled state. We put them in automatic start and rebooted the server. All services started but now Microsoft Exchange Service Host service terminating every 20 second and in application log we see the following error...
Watson report about to be sent for process id: 3384, with parameters: E12IIS, c-RTL-AMD64, 15.02.1748.026, M.Exchange.ServiceHost, M.Exchange.CertificateNotificationServicelet, M.E.S.CertificateNotificationServicelet.UpdateDataInMbx, System.ArgumentNullException, b164-dumptidset, 15.02.1748.026.

Anyone have a clue about this?EDIT: (SOLVED)
We found out that we missed to put World Wide Web Publishing Service to automatic. That service was also changed by the installer. After comparing the two servers in the DAG we could see what services that was automatic on the working server.
It would be great if the installer in someway could return the server to a working state if cancel button is pressed. Or Exit button that was our only option when the Retry did not work.
