Windows 10: windows 10 1903 upgrade setup will not recognize digital product key

Windows 10 1903 upgrade setup will not recognize digital product key --- Current install of Win 10 v1809


Multiple attempts at install, I did downloaded the .iso for upgrade and tried install from there, no change. How do I get the system to recognize my digital product key for this and future upgrades?

Product key not recognized

I want to thank everyone for taking the time to respond to my query. I have to say some of the suggestions assume a tech capability beyond me.

I think I will find the original receipt, go back to the shop, and ask them for the Product Key, then try again. I suspect it was an unauthorized copy. Maybe that will work.

 

Product key not recognized


According to my computer, Windows7 is activated and is a genuine product. But when I attempt to download W10, it does not recognize the 25 digit Product Key. I don't know what to do.

 

Cannot upgrade to Windows 10 - Unique Product Key situation

No... let me try again.

• Old computer is running Win7 Pro (SP1) with a Product key I have from a few years ago. The Product is activated already, but I do NOT use this computer at this point, so I didn't worry about using the Product key when moving to the new computer (see below).
  
• New computer is running Win10 Pro, with data and OS migrated from the Old computer, (same Product key as above), then Upgraded to Win10 (without getting a new Product Key).

What I am trying to do now...

• I want to upgrade the OLD computer (Win7 Pro) to Windows 10... using a new Product Key I just purchased.
• I have tried to do this internally, and also using the ISO burned to a thumb drive. But it does not want to work.
• Steps:
  • Start from USB drive.
  • Enter New Product Key (or click "I don't have one").
  • Install initiates and then tells me to restart from Windows and then open the installer again to continue.
    • At this point, I actually need to Quit the installation to restart the machine.
  • When restarted, I go to the USB drive and restart/resume the installation process.
  • I have tried to download and not to download updates, but when the installation fails, I see the message, "Something happened" and "Setup has failed to validate the product key".
  • NOTE This happens if I enter the NEW Windows 10 Product Key, or if I skip that step (which I assume means that it will use the old Windows 7 Key for the upgrade).
