Hi guys,
I am trying to install maker 8.1.15 on beelink SER, on windows 11, but looks like the license is not working. I have already to reinstall, downgrade to 8.1.14 but no success. Is it because the OS is not supported yet in maker edition?
the response: Unable to activate license.
License in use; no more activations allowed (code=4)
That wouldn't have anything to do with the environment. Did you deactivate the license on the prior computer?
The license is freshly generated, so no one has used it.
I just tested an install on my Intel NUC that I keep around for testing Windows.. 
Spec:
Edition Windows 11 Pro
Version 21H2
Installed on 10/5/2021
OS build 22000.593
Experience Windows Feature Experience Pack 1000.22000.593.0
I had no issue activating Maker Edition. You might try regenerating your activation token and trying again with the new combination of key+token.
EDIT: Alternatively, you might try "Invalidate" on your Manage Licenses section first:
OK, problem solved. Thank you for your suggestions, but I try a different network and try installing 8.1.14 and then 8.1.15 suddenly it worked.
