Unable to confirm the product license

[BaekEunSeok]

Hello,

Recently I changed my computer from MacBook air to iMac.
When I had the MacBook Air, I used the Parallels 11 but I have not signed out and I sold my MacBook Air...

Now I am trying to install Parallels but it is saying "You have reached the maximum number of activations available for your activation key. Please purchase a new product license.".
But this does not make sense to purchase it because my license is just one version behind of the latest version.

Please give me a solution how to handle this issue.

I have 2 license keys.
- Parallels 9 / Parallels 11 upgrade

Hello @BaekEunSeok. We have made some changes to the license key. Please re-attempt the activation now.
