ArcGIS Pro, AllSource, Drone2Map and RealityStudio require the Microsoft Edge WebView2 Runtime

Description

Note: 
To configure ArcGIS Pro versions 2.9 - 3.2 to use the WebView2 Evergreen Runtime, follow the steps in the article: How To: Configure the ArcGIS Pro Chromium WebView2 control to use the WebView2 Evergreen Runtime

Starting at the versions listed below, these Esri software products require the installation of the Microsoft Edge WebView2 Runtime, instead of relying on a fixed version of WebView2 that was previously provided: 

• ArcGIS Pro 3.3
• ArcGIS AllSource 1.2
• ArcGIS Drone2Map 2024.1
• ArcGIS Reality Studio 2024.2

On internet-connected Windows 10 and Windows 11 machines:

As of January 2023, the Microsoft Edge WebView2 Runtime is a pre-installed software package on all Windows 11 devices, as well as all Windows 10 devices running the Windows 10 April 2018 Update or newer. This means that if you're using ArcGIS Pro, AllSource, Drone2Map, or Reality Studio on an internet-connected computer with a Windows 10 or Windows 11 operating system supported by Microsoft, no action is necessary on your part; these software packages will utilize this installation of the WebView2 Runtime, and Microsoft regularly updates the Runtime with patches and security fixes via standard Windows Updates.

Note that if your Windows 10 or 11 machine is not connected to the internet, you may not have the WebView2 Runtime on your machine. To confirm whether or not your Windows User has the Microsoft Edge WebView2 Runtime installed, open the "Apps & features" window on your Windows machine and search for "WebView2". The WebView2 Runtime should be present in the results if your Windows User has access to the installation, as shown in the image below:

On Windows Server machines:

Unlike supported versions of Windows 10 and 11, machines with supported versions of Windows Server do not possess the WebView2 Evergreen Runtime as a pre-installed software package.

When attempting to install ArcGIS Pro 3.3, AllSource 1.2, Drone2Map 2024.1 and Reality Studio 2024.2 or newer on a supported Windows Server machine without the WebView2 Runtime present, the following warning appears before preventing their installation from proceeding, as shown in the next image:

"ArcGIS Pro/AllSource/Drone2Map/Reality Studio requires Microsoft Edge WebView2 Runtime (x64). To download and install Microsoft Edge WebView2 Evergreen Runtime, visit the Microsoft website or contact your system administrator. To install ArcGIS Pro for All Users (per-machine), you must also install WebView2 Runtime as per-machine. To do this, right-click the WebView2 installer and click Run as administrator."

Cause

Starting with 3.3 and future versions of ArcGIS Pro, and the versions of Drone2Map, AllSource, and Reality Studio listed above, users are required to install WebView 2 using the Microsoft-provided Evergreen Installer, which can be found at this link: WebView 2 Evergreen Installer

Solution or Workaround

You can resolve the warning seen during installation of ArcGIS Pro, AllSource, Drone2Map and/or RealityStudio by installing the Edge WebView2 Runtime separately. This can be completed by using the following workflow: 

1. Using your search engine of choice, search for "Microsoft Edge WebView2 Runtime" and select the top result.
2. Search for the "Evergreen Standalone Installer" download option - select the "x64" option to begin downloading the installer.
3. After the download completes, you must run the installer in the correct mode for it to be recognized by ArcGIS Pro: 
   • If ArcGIS Pro, AllSource, Drone2Map or Reality Studio were installed with the "Anyone who uses this computer" mode selected, you have a per-machine installation. This is the default installation mode and requires administrator permissions. To perform a matching per-machine installation of Edge WebView2 Runtime, right-click the "MicrosoftEdgeWebView2RuntimeInstallerX64.exe" file and select "Run as administrator".
   • If ArcGIS Pro, AllSource, Drone2Map or Reality Studio were installed with the "Only for me" mode selected, you have a per-user installation of the software and can install the Edge WebView2 Runtime in either per-user or per-machine mode. To install Edge WebView2 Runtime as per-user, double-click the "MicrosoftEdgeWebView2RuntimeInstallerX64.exe" file to begin installation of the Runtime.

Once the Microsoft Edge WebView2 Runtime installation is complete, you may proceed with installing these ArcGIS products normally.
