Windows 10 Insider build 16215 uninstalled Norton. I reinstalled Norton as a trial subscription. When I attempted to specify my product key, it was not accepted.
Norton does not support Beta programs and that is what the Insider program is. You can check to see if there is an EAP Board is active now. That is where it might be accepted. Read the Announcements on top of that board so you know how it works.
Thank you for your response. I fully understand the difficulty in responding to beta releases. The primary reason for the post was to inform others who might also encounter the problem. For me the solution was relatively simple, I simply rolled back the update to a previous version where everything again was working. This is not always an acceptable alternative for all users.
Pour ma part, je suis sous Windows 10 Insider build 16215 et je n"ai aucun soucis avec Norton Sécurity Deluxe 2017.
It is still good to report these issues, even if your insider build is not supported. This helps Norton to know that there is an issue with an upcoming Windows version.
