you have entered an upgrade key. Please confirm it with a key from the previous version

Hi,
I purchased a permanent license for Parallels Desktop 17 Standard Edition. Can I upgrade from this version to version 20 Pro subscription ?
 
I previously used the free trial version of Parallels, I have recently purchased a new Key and have
Parallels Desktop 18 for Mac Standard Edition, Permanent Edition. I've been trying to sort this out for days, using every option possible! I paid 54 pounds for this key and I can't use it it's extremely frustrating. When I get to the screen to install windows through Parallels I enter my purchase key and click Activate, it then asks me for my previous key which I do not have. I previously used a free trial version . If this is not sorted I want and expect a full refund! thank you
 
I have the same problem, I am trying to activate version 18, it appears to me to lead the code from the previous version, but even though I enter it, I get the error "THE PREVIOUS ACTIVATION KEY HAS NOT BEEN ACCEPTED" I have version 14 to 18, none of them work, I can not activate version 18

Hello,
We have reset your Parallels Desktop 18 license key.
Kindly try to activate your Parallels Desktop 18 again.
You may use either your Parallels Desktop 17 or 16 license key as confirmation key.
Thank you.
 
Hello Parallels,

Apparently I experienced the same problem as many users, namely I could not find license key in email from my original purchase. I kept upgrading that product for years, but I never even got to install Parallels desktop.

I tried today though, and after accepting my newest 'upgrade' license, installer asked for original license. So I went ahead and purchased Desktop for Mac Subscription (Pro Edition) again. I was able to successfully activate the product, but a windows popped up briefly asking if I wanted to use another license (possibly the one I already had). I said no and went ahead with the newer one from today.

Now when I login to my online account, I have two identical active subscriptions. What is going on?

Can I get a refund on one of them? If not, which one will be automatically renewed? It always did with the previous subscription.

Thank You very much.
 
Hello Parallels,

Any news on my case above?

Clearly you have my subscription data (original subscription purchased in 2021, and renewed ever since), as I can see it myself, but you forced me to buy another subscription simply because I could not find my original license key from 2021!!!

Thank you.
 
I purchased parallels activation key in 2023. I re-downloaded the parallel desktop due to black screen. I entered my activation key , message appears you are supposed to upgrade the key. It was a permanent one time download . Why is it asking me to upgrade ??
 
Hello! I have a permanent license for parallels desktop 14. Will it be enough for me to buy an upgrade to version 20 or do I need to buy a full license again?
 
I am going to install Parallels Desktop 18 on another computer soon. Will there be again that pain in the ... with license activation?
 
Hi, i just have bought a update version from parallels desktop 13 to 14 as suggested in my software but when i will put the key i have received the message "you have entered an upgraded key. Please confirm it with the key from the previous version" request my previous key that I put and receive always the message "The product key of a previous version of Parallels Desktop has been not accepted on the license server". How can I validate it? or please get refund to me.
I have this same issue.
