Hello ,
I have edge installed on my W10, but site designer doesn't seem to see it, because it asks me to download it to replace the old explorer 11.
Do you know how to do this?
Merci

I don't remember how it was in Windows 10, but I think Edge will be the one that opens if you try previewing in IE11. I'm used to SD always finding your installed browsers by itself, I have never done anything to make them appear under 'preview on'.

Merci beaucoup Inger

It sounds like the website isn't recognizing Microsoft Edge, even though it's installed. Try setting Edge as your default browser by going to Settings > Apps > Default apps, and selecting Edge under Web browser. This should fix the issue. If it doesn't, try clearing the cache or checking for updates.
