If you are on a Dragon Medical One 2021.4 release without having installed the Microsoft Edge WebView2 Runtime, a banner will be presented to remind your Administrator to install it by January 2022. New features that make use of the Microsoft Edge WebView2 technology will not be supported on the existing Microsoft Internet Explorer 11 control. As of January 2022, any updates to the windows mentioned above will result in unknown degradation of functionality.

Some Citrix environments exhibit issues that can cause the Microsoft Edge WebView2 Runtime process to fail to work as expected and to sometimes terminate with a message visible to end users. While this issue is external to Dragon Medical One, it does produce negative side effects causing the Dragon Medical One Hosted View (personalization and help window) to not display properly.

As a workaround, you can apply a configuration change to the Citrix environment to disable the Citrix Special Folder Redirection feature (SfrHook) for the Microsoft Edge WebView2 Runtime process. To do so, add the following registry keys to your Citrix environment configuration:

[HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\CtxHook\AppInit_DLLs\SfrHook\msedgewebview2.exe]
[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Citrix\CtxHook\AppInit_DLLs\SfrHook\msedgewebview2.exe]

A reboot is required for these changes to take effect. For Citrix documentation on these registry modifications see: How to Disable Citrix API Hooks on a Per-application Basis

Caution! Using Microsoft Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Use Microsoft Registry Editor at your own risk. Be sure to back up the registry before you edit it.

Microsoft .NET Framework version: Starting with the 2021 release series, Dragon Medical One requires Microsoft .NET Framework 4.7.2 (or higher). Machines that do not have this version installed will not be able to start Dragon Medical One. Please make sure that your environment is updated.

If Microsoft Edge WebView2 Runtime is not returned in the list of installed applications, follow these instructions to install it.

By default, the Evergreen Standalone Installer will autoupdate. In some circumstances it may be prudent to control the updates. This can be overridden via group policy or registry edits.

Some Windows security updates, settings, and third-party security programs may block necessary URLs to access some Dragon content. If WebView2 is installed and restarting Dragon did not resolve the issue, please see our troubleshooting post regarding Internet Options and Trusted Sites.
