Offline UAD Authorization

About This Page

This page explains how to authorize UAD-2 and Apollo devices when the host computer is not connected to the Internet. If the computer is Internet-enabled, see the online authorization instructions instead.

For complete details about the UAD registration and authorization process, see the UAD System Manual.



To authorize an offline UAD device(s), you will need:

  1. A USB flash drive or other external storage device
  2. A computer with an Internet connection and web browser

Note: Updating to the latest UAD software is recommended before proceeding.



1. Create URL link file on offline UAD computer


    • Open the UAD Meter & Control Panel application, then click the blue "UAD-2" button at the left side of the UAD Meter window. The Plug-Ins panel appears.

    • Click the “Authorize Plug-Ins” button in the Plug-Ins panel. The web browser opens with the required URL but it can't connect to authorization server (because the computer is offline).

Authorize Button



    • Drag the browser's URL icon to the Desktop. This action creates a weblink file on the Desktop containing the required URL.

Saving weblink file



    • Copy the weblink file to a USB flash drive (or other external storage device) so the required URL can be opened on the Internet computer.
