Installing Veeam Agent for Microsoft Windows in Unattended Mode

You can install Veeam Agent for Microsoft Windows in the unattended mode using the command line interface. The unattended installation mode does not require user interaction — the installation runs automatically in the background, and you do not have to respond to the installation wizard prompts. You can use the unattended installation mode to automate the Veeam Agent installation process in large-scale environments.

Prerequisite Software

During the product installation, Veeam Agent for Microsoft Windows automatically sets up the following required prerequisite components:

• SQLite database engine

Veeam Agent for Microsoft Windows 6.2 uses SQLite database instead of Microsoft SQL Server 2012 Express LocalDB. If you install Veeam Agent 6.2 on a computer with an existing SQL Server database, migration to the new database will be performed during the upgrade of Veeam Agent. If necessary, you can skip migration to the new database. To learn more, see Installation Without Database Migration.

• Windows Universal C Runtime Library

Veeam Agent for Microsoft Windows also sets up Microsoft .NET Framework 4.5.2 if it does not detect this component on the computer during the product installation.

In some cases, installation of prerequisite software requires computer reboot. This can happen, for example, if you have an earlier version of a prerequisite component installed on the computer and during the installation process this component is used by third-party software.

In this situation, unattended setup will install Veeam Agent for Microsoft Windows but will not start the Veeam Agent for Microsoft Windows service. After you reboot the computer, the Veeam Agent for Microsoft Windows service will be started and Veeam Agent for Microsoft Windows will be fully functioning.
