Just go to the XLN Online Installer from the Start menu > All Programs > XLN and run it. After it completes the scan and does some update checks, click on Register Products. You will be presented with the available updated along with XLN products you already have. I left the check boxs that asks where you purchased it blank, since someone here mentioned it can cause a problem if you check the wrong one; doing so had no effect on getting the ADpacks. Select the ones you want and hit the apply button. Done deal.
