Analytics Edge products are licensed to your computer, so when you upgrade to Microsoft Windows 10, all of your Analytics Edge licenses will stop working.
The Analytics Edge Basic Add-in has been updated (v3.5.3) to detect this and delete all of the old licenses. When you restart Excel, you will need to re-register/activate the product. Note that account login information saved for the connectors will be unaffected.
For the Analytics Edge Core Add-in and paid products like Google Analytics Pro Connector, you need to send an email to email@example.com to ask for your licenses to be reset for a new computer installation.
