The Microsoft Edge WebView performs much better than Internet Explorer and features enhanced compliance with modern browser standards including support of the full set of HTML 5 and ECMAScript 2015+. While it was cutting edge at the time, web development standards have continued to evolve.Īs we announced at Build 2019, to improve our support for web standards we are moving to an updated WebView control that is based on the current version of Microsoft Edge.īeginning with Office 365 version 9 and Windows 10 version 1903, Office Add-ins running on Office 365 for Windows will use a Microsoft Edge WebView as the runtime. Updates may not include or support all existing software features, services, or peripheral devices.Since the creation of the Office Add-ins framework, add-ins running in Office on Windows used a web viewer control that leveraged elements of Internet Explorer 11.

You agree to receive these automatic updates without any additional notice. Microsoft may need to update your systems to provide you with updates. UPDATES: The WebView2 software may periodically check for updates, and download and install them for you. PRIVACY: The WebView2 software is provided by Microsoft and it may collect information about the end user's use of the software, and send that information to Microsoft to provide services as disclosed in Microsoft's Privacy Statement at. If it still doesn't work then please contact us for support. The installer will then download and install the appropriate files for the WebView2 Runtime for your operating system.Īfter installation, please restart CSS HTML Validator and then try using an integrated browser view. Please download the Microsoft WebView2 Runtime installer and then run it. This is normally included as part of the Windows 11 operating system but if you're using Windows 10 then you may need to download and install the WebView2 Runtime (if it isn't already installed). The optional integrated web browser view (in 2022/v22+) requires the Microsoft Edge WebView2 / WebView Runtime in order to work. Note: The WebView2 / WebView Runtime is required only if you want to use the optional integrated web browser views in CSS HTML Validator 2022/v22 and above.
