Hi
Are you trying to install Windows on boot, or while logged into Windows ?
Seems if you try to install on boot, this is considered a full install of Windows rather than an update.
Try install while logged into windows, then Windows shouldn't ask for serial.
Also make certain you have downloaded the correct version of Windows, Either Windows Home or Windows Pro.
Thanks
Mine me won't install on boot nor will windows update install it, it fails, the only way I can install it is within windows. I tried to make a windows 10 ISO disk didn't install that way even using isobuster and virtual drive, so I tried just burning the files on disc and it won't boot from the disk it goes right into windows 7 start up, I have also put the files on a flash drive and attempted to boot from that with no luck. And if I start setup within windows 7 it wants a product key which windows 7 key will not work either, what other options do I got I can't get the discs to boot, nor the flash drive. But setup works great within windows Til it gets to the product key part. What can I do now?

In fact, you only need to use the older product key one time. After you upgrade from Windows 10 Home, the Windows 10 Pro digital license is attached to the specific hardware you just upgraded.
