Roll back to Version 16 not possible - Forces upgrade to 17

I have been running parallels from version 14 and been happy. Upgraded it to version 16 on a permanant licence for a while now. Got an email saying that version 17 was available as a free upgrade. I applied the upgrade, to then find out it was only for 14 days or pay for the upgrade.

I want to roll back to version 16 - I've downloaded it and installed - only to find that it forces you to upgrade or enter a licence key for version 17.

So, now i'm stuck without my parallels desktop with a fully paid licence key for version 16 which i cannot install. I've raised a ticket direct to support, but wanted to see if there are any suggestions here that might get me back and running a bit sooner.

 

I am on an annual renewal licence and when the message to say I can go from 16 (relatively stable with a few recuring problems running Windows 10) to 17 which apparently could speed up loading of Windows and other functions.

To be fair, I used to notice the fans on my MBP 16 goes on like crazy running Windows with an external monitor using HDMI or DP cables. The fans have slowed down, but still a slight whir when I am using Windows.

But it definitely does NOT load faster. In fact it loads slower by a noticeable margin. I don't know what's wrong and I can't roll back to 16 either.

 

Hello,
please use this link to download Parallels Desktop 16
and please let us know.

 

Is there an update on this? I tried to downgrade from 17 to 16 and it forces the upgrade to 17. I'm really tired of the driver issues with 17. My display driver constantly has problems. i never had those with 16.
