Uninstalling Veeam Backup Enterprise Manager in Silent Mode

You can uninstall Veeam Backup Enterprise Manager in the silent mode with a special XML answer file by using the command line interface. The answer file contains all the necessary uninstallation settings in the proper order and their thorough description.

Before You Begin

Before starting the uninstallation of Veeam Backup Enterprise Manager in the silent mode, consider the following:

• The user account that you use to run the silent uninstallation must be in the local Administrators group on the machine where the silent uninstallation will run. The silent uninstallation cannot be run under the LocalSystem and NetworkService accounts.

• If the user account that you use to run the silent uninstallation is logged on the machine using the network logon method, the silent uninstallation will fail. To avoid this, use an additional /SkipNetworkLogonErrors command line key. For example, it is required when the silent uninstallation is started using a remote PowerShell session.
• When configuring the answer file, remove or comment out unused [Optional] parameters. Otherwise, the uninstallation session will fail.
