Parallels 11 - Unable to confirm the product license

I'm trying to transfer one of my Parallels licenses from an old iMac to a newer MacBook Pro, but after deactivating and uninstalling it on the old iMac, I'm getting a message Unable to confirm the product license. You have reached the maximum number of activations available for your activation key, eventhough I've only activated that specific key once and was told I could transfer it when I needed to.

 

We have made necessary changes, try to activate again.

 

Sorry to reuse this thread, but we have also just upgraded our MacBook wiped and sold our old one and our new one after time capsule restore is saying it has reached the maximum number of uses. Please can you help us.

thanks
Mike

 

We have made necessary changes, try to activate it should work.

Hello!

Just tried to transfer my Parallels 11 license from my old MacBook Pro to a new MacBook Pro. I deactivated and uninstalled Parallels 11 on the old MacBook Pro. When I tried to activate Parallels 11 on the new MacBook Pro, I received this message: "Unable to confirm the product license. You have reached the maximum number of activations available for your activation key."

I recently upgraded to Parallels 12 on my iMac. Could this be related? Do I have to deactivate Parallels 12 on the iMac, in order to use Parallels 11 on the MacBook Pro?

Thank you!

Hello @Gerry_Percy ,
We have reset the activation limit from our end. Please go ahead and activate on your new Mac and keep us posted.

 

I have the same problem with version 10. All suggestions welcome.

 

We've reset the activation key. Please open Terminal (Finder > Applications > Utilities > Terminal) end execute this command: prlsrvctl activate-license-online for a successful activation.

 

Working. Thanks.
