Did you follow the instructions below for
resinstalling Edge (just downloading it isn't the same thing)? If so, I suggest you contact MS support:
Here’s how to reinstall Microsoft Edge whether you’re a Windows or Mac user:
Open any working browser. (Note: If you’re a Windows user and your Microsoft Edge is not currently functioning, to open Internet Explorer, type IE in the search box on the taskbar and then select Internet Explorer from the results. Or press the Windows logo key on your keyboard and then type IE in the search bar.)
Go to
www.microsoft.com/edge to download and reinstall Microsoft Edge.
5. Restart your computer
If there's still a problem, restart your computer, and then try reinstalling Microsoft Edge again. To restart your computer, select Start > Power > Restart .
6. Contact support
If you're still having trouble, contact our support team.
