Unable to Install Extensions on Microsoft Edge after Windows 10 Anniversary Update
on Windows

So I installed Windows 10 Anniversary Update. On the previous Windows 10 versions, I was using Microsoft Edge and got used to it. After the update was run, I can’t install any extensions on Edge. When I click on the ‘Extensions’ option on Edge and select an extension I prefer using, it does not download. I’m informed that there is a problem with it and that I have to reinstall it. I tried to do so, but reinstalling doesn’t work either. Could you please tell me what should I do? Is it possible that Windows update disabled Edge extensions purposely?

In the meanwhile, Microsoft does not officially confirm this issue to be a system bug, but, nevertheless, provide several methods that can help fixing this problem. Therefore, if you can't use extensions on Microsoft Edge, try one of the following methods:
