Here at Neowin, we frequently report on the experimental additions and modifications Microsoft adds to its browser via the Canary Channel. Using Edge Canary and testing daily updates carries with it a high chance of encountering malicious flaws and instability. One of these problems severely affected Canary users and rendered the browser inoperable.
Multiple testers report that after installing the most recent update, Edge Canary would not launch. Microsoft swiftly retracted the problematic version, leaving numerous customers with a flawed web browser. If you are one of these unfortunate insiders, here is how to revive Edge Canary.
To open Edge Canary quickly, right-click its icon on the taskbar and select InPrivate Mode. Once Microsoft releases a new version with the patch, it will suffice to launch and update Canary. If you require a permanent solution, follow the procedures below to restore the prior Canary version:
- Download offline installer for Microsoft Edge Canary 105.0.1334.0.
- Open the downloaded file using 7-Zip or another archive management program.
- Open the folder contained within the executable file and copy its contents.
- Navigate to the C:\Users\Your username\AppData\Local\Microsoft\Edge SxS\Application\105.0.1336.0.
- 105.0.1336.0. You may be using version 105.0.1335.0 rather than 105.0.1336.0.
- Replace existing files with the copied files if necessary.
- Microsoft Edge Canary should now successfully launch.
This incident serves as a further caution against using Canary as your primary browser. Microsoft permits running multiple Edge channels concurrently, thus it is better to use a stable edition for daily work and Canary or Dev for testing purposes.
