I’m getting “CCleaner cannot start” - requires MS Edge WebView2 Runtime.
I know Win10 is not supported by MSoft, but CCleaner has run fine on it until recently. Is there a work-around to continue using CCleaner, maybe dropping back to version 6?

It’s a known issue with WebView2 Runtime being missing, corrupted, or not being up to date.
It isn’t CCleaner that is the problem here.
The problem is that "WebView2 Runtime’ isn’t working properly on your machine.
You may find that other things will also stop working, or stop displaying properly.
You need to repair or reinstall the Webview2 Runtime on your machine and then CCleaner will be able to run again.
