Couldn't find a compatible Webview2 Runtime installation to host WebViews.

[starkdm]

Why am I getting this exception on Windows Server 2022, while my work computer (Windows 10) has the same WebView2 Runtime version installed and everything works fine?

EnsureCoreWebView2Async throws:
Microsoft.Web.WebView2.Core.WebView2RuntimeNotFoundException: Couldn't find a compatible Webview2 Runtime installation to host WebViews.
InnerException: System.IO.FileNotFoundException: The system cannot find the file specified. (0x80070002)

Installed on the server from here (both x64 x86)

Hi @starkdm!
Thanks for your reply. Could you help to test if the WPF sampleWPF sample could run ok in your Windows Server 2022 computer and check if the .Net SDK version is corresponding to the run time version?

@yunate WPF Sample is targeting to .NET Core 3.1. I am target my project to .NET Core 6, but I am download latest WebView2 NuGet package version. In WPF Sample I see 1.0.1414.

I had similar issue and the solution was to run the installer as administrator so it is installed machine-wide. Otherwise it was installed for user that run the installer and when running a process as different user I was getting this exception.

I have the issue now; running the installer to install machine-wide did not help.

@Renakos what is the exception you're getting? Could you paste the whole error + sample code?
