I have a PD for Mac Pro Subscription. I downloaded PD 26 and installed it. When I tried to activate, I get an error "Unable to verify the license signature". I have tried using "sudo chflags 0 /Library/Preferences/Parallels/licenses.json" in Terminal but it did not work.
Hello @DennisM5 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,
I AM HAVING THE SAME ISSUE AFTER TRYING TO INSTALL THE LATEST PARALLELS UPDATE. DURING THE PROCESS IT TOLD ME TO ACTIVATE MY LICENSE. I CLICKED ACTIVATE AND I GET THIS UNABLE TO VERIFY MESSAGE DISCUSSED IN THIS FORUM. I EVEN MANUALLY ENTEWRED MY PRODUCT KEY AND GOT THE SAME MESSAGE. VERY FRUSTRATING - LOCKED OUT NOW.
Same here - no activation under 26.1.0 - amazing how they break things regularly with no consequences.
Same problem here: just updated from 26.0.1 PRO to 26.1.0 and can lo longer open it due to a license verification issue. Hope this gets fixed ASAP.
Same with me. I opened support ticket 4 hours ago, and still no answer. Very frustrating when someone use VM in production environment.
Having the same issue, Upgraded to the latest version today, now it won't activate and I can;t get any work done! Please fix this ASAP!
