I just updated to the latest version of windows 10 Developer Edition Build18975 rs prerelease 190830-1502. Now when I open Word, the program goes searching for a product key but can't find it. I can then enter my existing product key (obtained from my subscription to MSDN) but Office 2013 will not recognize the reg key. Instead I receive an error message with the System Error Code: -1073423314.
This update to WIN10 was a major release and created a windows.old folder etc. I have a strange feeling this happened once before some months ago.
Would be most grateful for anyone's kind advice. I don't want to waste yet another reg key that is unnecessary.
