Windows Activator Version 10 No Religion

Hi, I upgraded from win 7 pro to 10. My laptop worked fine for weeks, then refused to start windows one morning. I tried the repairs available (advanced options, etc). I then downloaded the ISO file for win 10, that contains all the win 10 versions, I retrieved the win 10 pro product key from my drive, but during the win 10 installation it says the the key is invalid. Can anyone advise me, please. Thank you.

We use multiple hardware platforms with this image. We have MAK keys available when we check the counts. The key is valid. cannot activate the version of windows. it says there is a valid digital license for Windows 10 Pro. It identifies the version of windows as Windows 10 Pro. Did not have this issue until the 1703 update/version came out.
