Hi, my PD renewed itself automatically yesterday. However, when I restarted my mac and opened PD, it asked me to activate my PD. The activation just failed as it said "You have entered an upgrade key. Please confirm it with a key from the previous version." But I only have one key in my account so I repeated that key in the second line. Then I have prompt like the attached file. I have tried to re-log in my PD account and then activate again, but it does not help.
Hi @zhao1, I believe helped you activating Parallels Desktop Pro Upgrade on the phone session. Please let us know if you still have any issue in activating the license and we can help in a personal message.
Hello - I have this very same problem - I have tried countless times to activate my subscription, I cannot find a key from the previous version. When I go to the documents 'details' next to 'invoices' on my account to look back, I either get the new, same key again or it is blank IE there is no key written. Could you help me in this also? Thanks in advance.
Hi @LORENZO6 , the license key which you are trying to activate now, was it activated anytime previously?
Hello Arun thanks for your message. No I don't think so - when I am asked to enter my activation key (upgrade key) this is accepted on the activate parallels welcome screen. It then asks me for a key from the previous version, and produces a new line for me to enter this, but I cannot locate key this in my online account when looking at my purchase history, despite having bought the software a few years ago.
