Scan Agent ships with two installers: a Scan Agent User installer and a Scan Agent Administrator installer. The only difference between the two installers is that the Admin installer also allows you to install Scan Agent as a service. In order to run the Admin installer, you need to have Administrator privileges as the installer has to create a service. If you do not plan on running Scan Agent as a service you can just use the Scan Agent User Installer (note it does not require Administrator privileges).
