Hi, I just did an upgrade from Parallels 10 do 12. I'm using the normal version. I would like to change it to the Pro version (because of Vagrant integration). How can I do this? The second problem is, that I'm not able to activate the Toolbox with Parallels key. It says, the key was already used for activation.
We see that you have made the purchase recently and suggest you to get the refund for the normal upgrade and purchase a Pro upgrade. You can use the new key to activate Parallels Toolbox.
