Issue opening Power BI

[Victor94693]

Hi,

I've always used Power BI Desktop without issue, but from yesterday I've suddenly got this error message while opening PBI:

"Unable to cast to Microsoft.Web.WebView2.Core.Raw.ICoreWebView2Settings3.
This may happen if you are using an interface not supported by the version of the WebView2 Runtime you are using.
For instance, if you are using an experimental interface from an older SDK that has been modified or removed in a newer runtime.
Or, if you are using a public interface from a newer SDK that wasn't implemented in an older runtime.
For more information about WebView2 versioning please visit the following: https://learn.microsoft.com/microsoft-edge/webview2/concepts/versioning"

I've already tried to unistall and reinstall PBI Deskop but the issue remains.

Can you help me?

Thanks

Hi

I just got the same error. But I could solve it by just repairing the version of webview2 runtime that was already installed. This installed the latest version automatically which should be version 130.0.xxxxxx. Before the repair I had version 120.x.xxxx or something like that (from march 2024).

You can always ask Copilot for help, below is a reply I got when I asked how to uninstall an older version of webview2. This works for repairing too, just choose "repair" instead of uninstall.

To uninstall an old version of WebView2, follow these steps:

1. Open Settings:

   • Press Windows + I to open the Settings app.

2. Navigate to Apps:

   • Go to Apps > Apps & features.

3. Find WebView2:

   • Scroll through the list or use the search bar to find “Microsoft Edge WebView2 Runtime”.

4. Uninstall:

   • Click on the entry and select Uninstall.
   • Follow the prompts to complete the uninstallation.

Thank you very much! It works!

Have a good day!

Verify if you are using the latest version of Power BI Desktop, as updates often include patches and enhancements that may resolve compatibility issues.

If your network operates through a proxy server or firewall, it may be blocking web requests from Power BI Desktop. To avoid this, add the following domains to the allow list in your proxy or firewall settings.

Additionally, as noted by @Greg_Deckler , verify that you have the most recent Microsoft Edge WebView2 runtime installed on your system. For more details, refer to the following link:

Hi, thanks for the reply.

I've already checked Power BI version and the presence in the allow list of firewall.

I'm not a developer so I have some difficulty to fully understand the content of the link https://learn.microsoft.com/en-us/microsoft-edge/webview2/concepts/versioning.

Anyway, in one of the thread that you reported I've read that one user solved the issue: "I discovered the cause of my issue- an older version of WebView2 Runtime on my machine somehow didn't get deleted or overwritten. I was eventually able to delete it and all was well. ". But how I can unistall the possible older version of WebView2 Runtime?

Thanks
