GP App is not displaying embedded WebView2 browser for SAML authentication on Windows systems

GP App 6.2.3+ is installed on a Windows system, but it does not pop up the embedded WebView2 browser when redirected for SAML authentication, and gets stuck at Connecting state

The issue is seen on a Windows system that has an older WebView2 version installed (usually happens when a device is newly imaged)

GP App 6.2.3 & 6.3.x

SAML Authentication

Embedded Webview2 Browser 

PAN-OS GP Portal and GP Gateway

Windows system

Either the Webview2 version is old or the Windows system is preventing the running of the Webview2 process

NOTE: This article is specifically written for a scenario where the installed Webview2 version is old

Check the PanGPA logs and see what version of Webview2 is installed, what is the Installation Directory Path, and if there is any Error in initializing the Webview2

Here is an example, where the Windows system has Webview2 version 100.0.1185.36 installed under the installation Path c:\Program Files (x86)\Microsoft\EdgeWebView\Application\ and PanGPA could not initialize the Webview2 and throws an error like Cannot get ICoreWebView2_13 Interface

Please make sure the Windows system is running the latest and stable Webview2 version

For Webview2 installation and upgrade, please check with your System Administrator or IT

Usually, upgrading Microsoft Edge upgrades the underlying Webview2
