I am trying to activate Parallels Desktop for Mac, but get the follwoing error message:
In this screen you can enter an activation key only for Parallels Desktop Business Edition.
You clicked on the Business Edition button, which should be used only by Parallels Business customers.
Click Go Back and complete the registration procedure. Create a Parallels account or log in to an existing one. When the activation window appears, enter your activation key. See KB 123277 for more information on the registration process.
