Dear Parallels Support Team,
I am unable to reactivate my Parallels Desktop 18 perpetual upgrade license after reinstalling macOS on the same Mac.
When I enter my Parallels Desktop 18 activation key, I am prompted to provide the activation key for a previous version. However, after entering my original previous-version key, I receive the following error message:
"The previous activation key has not been accepted by the license server."
Both keys were previously used successfully as part of the same upgrade path before I reinstalled macOS. I am not attempting to use the license on multiple Macs.
Could you please:
Verify whether the two license keys have a valid upgrade relationship;
Check whether the previous installation is still occupying the activation;
Reset or restore the activation eligibility if necessary; and
Advise me on how to reactivate Parallels Desktop 18 on this Mac.
My details are as follows:
Current product: Parallels Desktop 18
License type: Perpetual upgrade license
Mac model: Apple M1 Pro
order number: 402360299 / 334401216
For security reasons, I have not included the complete activation keys in this email, but I can provide them through a secure support channel if required.
Thank you for your assistance.
Best regards
