Addressing the impact of the WebView2 and Chromium addons

Hello Ares Users,


Ares Client Crashing - Background

There have been several reports surrounding the ILLIad Client crashing so we’re deciding to take preventative actions for Ares as well. After further investigation, we have found Microsoft released an update on Microsoft WebView2 to version 121.0.2277.83. The update seems to be affecting Chromium and WebView2 addons by causing the Client to crash.

This is because the update no longer allows users to run both Chromium and WebView2 browsers at the same time. As a result, Ares users on version 5.0 may experience client crashing when using Chromium-based client addons.


What we’re doing to resolve the issue

Atlas Systems is working to update any supported client addons that have not yet been converted from Chromium to allow support for WebView2. We will post updates as the addons become available. Note: If you are running any addons that have support for WebView2 with Chromium as a backup, these addons will be fine to leave in place.

In the meantime, we recommend verifying you’re using the latest version of the addon and turning off the affected addons. We do not recommend rolling back to the previous version of WebView2.

If you a running a custom addon for your institution, please contact for assistance converting the addon to WebView2.
