The configure the DVT license set $DVT_LICENSE_FILE, $DVTLMD_LICENSE_FILE or $LM_LICENSE FILE environment variables with the address of the license server (port@host) or with the path of the license file. The variables will be checked in order and the first non-empty value will be used.

The license variable must be set before starting DVT.

A license is checked-out when you open a DVT project and start using DVT's features.

To see if the license works open a predefined project and go go to menu Window > Preferences and inspect the DVT > License.
