Cannot Verify License Signature after Parallels Desktop 26 upgrade

I have 2 subscriptions to Parallels Desktop and was running the current version (20.4.1). I upgraded one machine to 26 and upon attempting to activate, I repeatedly get the dialog below. I have logged out and logged back in. Uninstalled and reinstalled Parallels. I am currently dead in the water. This is the only support that is offered to me (even though it says I can have phone and chat support as a subscriber).

Help

 

Hi,
I have the same issue. I contacted support by chat and it is a known issue which they are working on. I have reinstalled version 20 and relicensed ok.

 

Same issue for me

 

Me as well. Unfortunately it deletes the old Parallels version 20, which I must go find, download and reinstall now.

Suggest to anyone seeing this before upgrading: DO NOT UPGRADE until a resolution is posted here.

 

Same issue, had to reinstall Parallels 20, not a good experience.

 

Looks like the issue has been fixed in a new version of Parallels Desktop 26 Pro. I have just upgraded from V20 to V26 and now it licenses up fine.
