I bought Parallels Desktop 9 for Mac at the first time around 3years ago then I upgraded it to Parallels Desktop 11 for Mac Upgrade in November 2015.
I reset my Macbook today and wanted to install Paralles Desktop 11 but I couldn't do that. I've just installed only trial version on my Macbook.
Then I tried to put my license key for PD11 to complete the installment several times but your dialog box showed 'it's just an upgrade key and must put the previous key in it.'
I don't have any idea to solve it because no matter how I'm taking a look around on my previous emails and documents from your company to find my PD9 key I can't.
Please help me out.
Thanks in advance.
