UPDATE: The issue is Fixed. An error occurred while checking for updates: Failed to cache the downloaded installer. Error: 0x800b0109. (error code 7: 0xA043050D).Version 78.0.274.0 (Official build) canary (64-bit) Trying to update my Canary and i get this error. on my laptop which runs a non-insider Windows OS and Edge Canary i'm getting the same error.computer restart does not fix the problem.

Trying to download and install Edge canary in Windows Sandbox also fails with the same error.now i'm sure no uninstall leftovers is preventing reinstallation.I'd suggest not uninstalling your Edge cause you wouldn't be able to install it again ¯\_(ツ)_/¯Elliot Kirk

Because they removed the problematic update, i could reinstall Edge canary again from Internet.

Mine is on .276 with no problems HotCakeX .

Hi, yup it got fixed today for me too

Jacques Van de Meerssche Well you can run multiple startup pages along with that one. I have that one startup page because I don't have any other specific pages to open too. Technically Edge does check for updates when you enter the browser, and Edge has a scheduler set in your task schedule to do the same:

HotCakeX Yup, got the same error trying to update. Gave it a couple more tries and now it says I'm on the lastest - Version 78.0.274.0 (Official build) canary (64-bit). So I have to assume the issue is on the Microsoft side of things and they've pulled/stopped the lastest version.
