How to manually update the WebView2 Runtime?

[ajtruckle]

User is running Windows 10, 64 bit.

My application won't run and shuts down.

They are using:

• WebView2 Runtime Version: 108.0.1462.54
• WebView2 SDK Build: 1661.34

I am using:

• WebView2 Runtime Version: 111.0.1661.62
• WebView2 SDK Build: 1661.34

There is quite a difference between 108.0.1462.54 and 111.0.1661.62. How can I get it up to date?

Think I found the solution on the internet:

To install or update the WebView2 Runtime:

1. Go to page https://developer.microsoft.com/en-us/microsoft-edge/webview2/.
2. Scroll down to section Evergreen Bootstrapper, select Download > Accept and Download.
3. Find the executable file in your Downloads folder, right-click it and select Run as administrator.
4. Enter your administrator credentials. The installation starts and is completed in the background.

After I ran this my runtime went from 111.0.1661.62 to 112.0.1722.34. I am now checking with the user in question.

By the way, according to this link it does say:

To keep WebView2 up to date with the latest security and reliability updates, WebView2 Runtime uses its own automatic update process, separate from the update channel used by Microsoft 365 Apps. WebView2 Runtime is updated approximately a few times each month. Updates usually range in size from 5 MB to 30 MB, depending on the type of update. Differential updates and Delivery Optimization are used where possible. For information about managing these updates, see Managing WebView2 applications.

The user has now managed to update to the latest runtime and my software runs again. This begs the question:

Why was his runtime not up to date if the operating system is supposed to manage it? 🤔

According to my current test, WebView2 is installed on the Win10 machine through Edge's task plan/service (the actual test should be task plan) #3317

I guess that the relevant task plan may not be executed, or EdgeUpdate is not installed or the file is missing

@ajtruckle Can you collect the installation log?

[ajtruckle]

@novac42 We have asked this before. There is no simple way to obtain a log.

WebView2 Runtime is designed to auto update, using scheduled tasks. Auto update would not work if the IT admin setup policy to block it, those scheduled tasks are disabled. We need Edge update/installer logs to tell us what's going on.
