Hello, I got used iWork20Pro with Win11, and I had download an Windows 10 image from https://www.alldocube.com/en/firmware/alldocube-iwork20proi1025-firmware-download/

It was installed witout problems. everything is work, but it can’t do activation. Message on troubleshooter says – it can’t find the license key.
What should I do with it? I dont want  to buy another Windows home edition license
