Parallels 26 Won't Activate

[JulsS]

I installed Parallels 26 but it won't activate. When I click Activate it gives me an error "Unable to verify the license signature." If I click the Enter a new key button, I can enter my key and the green check mark displays, but when I click Activate, I get the same error message. I can't get into any of my VMs.

Same here. I've tried to start Parallels and i have activation error - "Unable to verify the license signature."

I had the same with one license key while another key worked fine. Today both keys work fine, but not sure if someone fixed something since I created a ticket about the problem yesterday.

Hello,
Please note that this is a known issue and we are currently investigating.
As a temporary workaround for now, please uninstall Parallels Desktop 26 (open Finder > click on Applications > right click Parallels Desktop and move to bin). Then download and install Parallels Desktop 20.4.1 from:
https://download.parallels.com/desktop/v20/20.4.1-55996/ParallelsDesktop-20.4.1-55996.dmg
Regards,

Parallels support notified me that an issue was fixed on their licensing server. I was able to activate my Pro licenses with 26.0.
