Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.The Parallels 7 Activation code will not work on Parallels 10. You have to buy Parallels 10 Activation code. You can buy Parallels 10 for Mac from here : http://buy.parallels.com/329/purl-pd10f?x-source=site&x-locale=usYou have to buy the Parallels 10 for $79.99You are not eligible for the Parallels upgrade price $49.99 since that is available only for Parallels 8 or later users.After buying Parallels 10, you will get the activation code via email. Use that code to activate Parallels.If you have any questions or would like any additional information, please don't hesitate to ask.
I was offered a free upgrade - I did not want an upgrade - Parallels 7 worked until I upgraded the operating system to Yosemity - when I was offered an upgrade - and when I checked my friend with Parallels is still using parallels 7 having had the Yosemite upgrade to his computer - admittedly not as old as mine
Yosemite is a free upgrade from Apple, but Parallels 10 isn't. Parallels 7 is not officially supported on Yosemite. See here : http://kb.parallels.com/en/121895There are some compatibility issues with Yosemite and Parallels 7.I'd recommend you to upgrade to Parallels 10 if you want to use it with Yosemite without any problems. I know this is not the answer you want to hear, but the problem is with Parallels 7 as it is not designed to work on Yosemite. Upgrading to Parallels 10 is the recommended solution from Parallels.
At least I now have parallels working
Many thanks for your help
