you have entered an upgrade key. Please confirm it with a key from the previous version

Yes, you have Parallels Desktop 14 one-time upgrade key. You have to use Parallels Desktop 12 key as the previous key to complete the activation.

 

I tried that, even though the program never asked this before, the Parallels 14 key was enough. When I use the Parallels 14 activation key and Parallels 12 as a previous version key I get the following error:

The previous activation key has not been accepted by the license server.

Please make sure you have entered the key correctly. Your activation keys are stored in your Parallels account. If you don't want to bother yourself with numerous activation keys and upgrade procedures in future, we recommend that you purchase a subscription to Parallels Desktop.

 

Changed some settings again, please check the issue and share any results with us please

 

Thanks, but still the same error pops up, I even tried removing parallels completely. What can else I do?
"The previous activation key has not been accepted by the license server."

 

Could you provide us please with the screenshot of the error message please?

 

Sure, here it is

 

Thank a lot, changed settings once again, please check the issue.

 

Still the same, maybe I'm using wrong serial numbers, I don't know anymore

 

Any news? I still cannot run windows ...

 

Anything?
