Did you ever start Power BI Desktop and this error showed-up out of nowhere?!

Clicking “Install now” seems to be doing something but in the end it fails saying Microsoft Edge Webview2 Runtime is already installed?

Restarting the machine does not help, don’t bother trying 🙂

Uninstalling and installing Power BI Desktop again – same issue.

Ok, let’s look into WebView2 and what’s wrong here…

According to Event Viewer: Windows is unable to verify the image integrity of the file \Device\HarddiskVolume3\Program Files (x86)\Microsoft\EdgeWebView\Application\111.0.1661.62\prefs_enclave_x64.dll because file hash could not be found on the system. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.

In plain English this means there is an issue with WebView2 and not Power BI. But wait, we already knew that, right? And we already clicked “Install now” and nothing happened, right?

Ok, let’s go to the Apps and uninstall and reinstall WebView2 I thought initially. But wait, the app does not have the uninstall option, only Modify.  

Clicking Modify started a new small window and I could see it downloaded the installer and then started installing it. With no other messages, that small window closed unexpectedly, with no success or failed message… Rolling over my eyes, I opened Power BI Desktop and it started fine this time!
