Problem Validating Win 10 with Product Key

[lbeck]

I used MDADiag tool to generate the report shown in the attachment. The report did not allow copy so I cut and pasted the graphic. The report also generated the error "failed to create output files" shown below the report. Here's the history of my OS versions:

• Dell Inspiron came with Vista
• I updated to seven pro a couple of years ago using an OEM disk purchased from Amazon
• The computer has been running happily with 7 Pro
• I had mucho problems upgrading to Windows 10 with lots of starts and non-finishes
• I finally got Ten to install after saving my data and doing a clean install using the Windows 7 Pro OEM disk, but it says that I need to activate my copy. Ten is running fine now

I used ShowKeyPlus utility to reveal my product key, and the key was generated as shown in the other screen capture.

As far as i know MGADiag doesn't work for Win 10.
