Exchange 2013 – Setup cannot continue with the upgrade because the ‘bbwinsdir’ () process (ID: xxxx) has open files.

If you’re upgrading Exchange 2013 and you run into a few snags because of open files or processes running, they’ll most likely be your backup processes.

For Barracuda, the error will be:

Setup cannot continue with the upgrade because the ‘bbwindir’ () process (ID: xxxx) has open files. Close the process and restart Setup.

For BackupExec, the error will be:

Setup cannot continue with the upgrade because the ‘beremote’ () process (ID: xxxx) has open files. Close the process and restart Setup.

To fix this, simply hop into your services and stop Backup Exec Services or Barracuda Backup Services. You won’t have any trouble the next time you attempt to run the update.
