I upgraded a computer and reinstalled Parallels Desktop for Mac on it. Parallels Desktop gave me the option to "Activate This Mac", noting that it would deactivate the previous install, which is what I wanted to do. Parallels Tools, however, won't activate on the new Mac. How do I reset the activation for Parallels Toolbox, as it comes with Parallels Desktop? Is there somewhere in my account where I can deactivate devices on my own?
