I was upgrading Exchange 2007 with Exchange 2007 SP2 on a client exchange server this evening and came across the error “Setup cannot continue with the upgrade because the ‘beremote’ () process (ID: 1876) has open files. Close the process and restart Setup.
The problem was a result of having Veritas Backup installed on the Exchange 2007 server. The service “Backup Exec Remote Agent for Windows Servers” was locking the process and preventing the Exchange 2007 SP2 setup from running. I had to go into Services and stop the “Backup Exec Remote Agent for Windows Servers” service. Once I stopped this service I was able to proceed with the installation of Exchange 2007 SP2.
Was there not someting in the “Prerequisites for Installation for Exchange Server 2007 SP2″ that alluded to stopping all process that may have a lock on associated files &/or processes?
The nice thing the MS Exchange team has done is that it will stop all Exchange processess. In most exchange deployments you would not typically add another application to the server.
