Error "Some of these characters can't appear in the product key." Windows 11 pro

Windows 10 - I try to enter product key, but "Some of these characters can't appear in the product key"

I recently installed Windows 10 with a legal download of the Iso file. When I open settings, there is a link to a setting labeled, "Windows isn't activated. Activate windows now." But if I try to enter my product key there, it says some of these characters can't appear in the product key. I have found out that the 015 AEIOU LNSZ characters can't be used, but on my other working computer, that is the listed product key. How can I fix this?

Upgrade using a Windows 10 Pro product key To upgrade from Windows 10 Home if you have a Windows 10 product key:

• Select the Start button, then select Settings > Update & security > Activation.
• Select Change product key, and then enter the 25-character Windows 10 Pro product key.
• Select Next to start the upgrade to Windows 10 Pro.

 

Windows 11 Home to Pro upgrade

Want to upgrade 11 Home to 11 Pro. Tried download, but apparently files transferred were for 11 Enterprise. This will not activate; error is "invalid digital license or product key". This is on a new Surface. How to proceed?

Can withdraw/delete this. The suggestion to downgrade - listed below - with a 'fake' windows 10 key works.
