Before upgrading to Velocity v3.8.5 from a pre-Velocity v3.7 release, you must register your Velocity software and obtain the necessary license(s). See the Velocity Licensing topic for details. Existing Velocity users moving from v3.8.4 to v3.8.5 must use the Velocity Update Wizard instead of the Velocity Installer. For more information, see Updating from Velocity 3.6 (or higher) to Velocity 3.8.5.
