ArcGIS Pro 3.3 adopts .NET 8 and WebView2 runtime.

ArcGIS Pro 3.3 is a minor release set to be available this month; May 2024. It has many new features and is compatible with ArcGIS Pro 3.x versions. To be ready for this, we want to inform you about the two primary installation prerequisites: .NET 8 and WebView2 Runtime. We can recall that ArcGIS Pro 3.2 ran on Microsoft .NET Desktop Runtime 6.0.5 or a later patch release. If Microsoft .NET Desktop Runtime 8.0.x (x64) is not installed on your machine, you will not be able to install ArcGIS Pro 3.3.

Microsoft Edge WebView2 Runtime is a required component for ArcGIS Pro 3.3 to display HTML and JavaScript content in the application user interface. You can easily check to see if you already have it and, if needed, install it using the steps that will be outlined in this blog.

Install Microsoft .NET Desktop Runtime 8.0.x (x64)

Stay ahead of the curve by installing .NET 8 on your machine. However, if you do not have admin privileges, you may initiate a service desk request or reach out to your IT support team and include a polite request to install the new .NET framework.

here’s a straightforward guide to installing .NET 8:

Visit the official .NET website at

Head over to the downloads area and find the installation package for .NET 8.x.x. Opt for the x64 version among the available installers.

Download page for .NET Desktop Runtime 8.0.x

Follow the on-screen instructions to initiate the installation process.

It takes well under one minute to successfully install .NET 8.

.NET Desktop Runtime 8.0.x (x64) installation was successful.

Once the installation is complete, you’ll be equipped with the latest features and improvements offered by .NET 8, ready to enhance your development experience.

Check if WebView2 Runtime is installed.

If you have Windows 10 or Windows 11 and internet connectivity, chances are you already have Microsoft Edge WebView2 Runtime installed. To verify, check your Apps and Features list for ‘WebView2’. If it’s there, you’re all set, and no further action is required.

If you do not already have WebView2 Runtime installed, you can download and install it from this link.

Accept the terms and conditions and proceed to download.

Choose the Evergreen Standalone Installer (x64).

The installer will automatically detect and install the latest version of WebView2 Evergreen standalone on your machine. You do not need to restart your machine after the installation.

IMPORTANT By default, ArcGIS Pro is installed per-machine to the following location: <System Drive>\Program Files\ArcGIS\Pro.  If that is where you have installed ArcGIS Pro, be sure to right-click the MicrosoftEdgeWebView2RuntimeInstallerx64.exe in your Downloads folder and choose to Run as administrator.

Finally, you can install ArcGIS Pro 3.3!


Microsoft .NET Desktop Runtime 8.0.x (x64) is a prerequisite to install ArcGIS Pro 3.3. This sets the stage for a smooth installation process and optimal performance and user experience of ArcGIS Pro 3.3. We hope this helps you get ready to enjoy all the fantastic new functionalities that await you in ArcGIS Pro 3.3.
