I have this very early version and try to register it under my account. The serial number is not valid when I input it into license key. How can I register it? Also, can I use this version and buy an upgrade to 16?

Just get a new Mac Big Sur to replace a very old mac. Tried to register license key by Parallels desktop 3.0 serial number but it shows wrong licese format. Do I have to install 3.0 into Big Sur Mac to update to 16? Can I just get an upgrade license to 16 from 3.0? thanks

Thanks for your quick help. My 3.0 serial number format is xxxxx-xxxxx-xxxxx-xxxxx-xxxxx (only 5 characters each group) and it won't let me active after upgrade key screen. As KB article KB115424, In Parallels Desktop 14 and below, the output will give you the serial line with numeric codes in the following format: The more activation keys you used on the Mac, the more codes you will see in the Terminal. xxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx The more activation keys you used on the Mac, the more codes you will see in the Terminal. Copy the contents of the serial line and send to Parallels Support. It went to support home page after click above support link. How I can reach support team upload my serial number? tks
