Hmm, so that error window most likely means that the webview2 installation failed.
No idea if it was tauris install script or yours (main.wxs) as it should try to run both scripts (because skipWebviewInstall is disabled).
But i also have no idea about wix, just trying to give you a hint to where it fails :/

[lucasfernog]

Seems like we need an alternative for Windows 7 since powershell isn't available.

[lucasfernog]

Let's see if https://github.com/MicrosoftEdge/WebView2Samples/blob/master/SampleApps/WV2DeploymentWiXBurnBundleSample/Bundle.wxs approach fixes it.

[lucasfernog]

Can you see if this installs correctly on Windows 7? It's an alternative approach using the Tauri API example. @charmfocus
installer.zip

[FabianLars]

Maybe my win7 VM is broken again (it shouldn't as it's a somewhat fresh install), but i get:
"Setup Failed
One or more issues caused the setup to fail. Please fix the issues and then retry setup. For more information see the log file
0x80072f7d - Unknown Error"

This is the same issue some people had in discord with the powershell script, where it didn't use TLS(1.2). for example the discussion around this message: https://discord.com/channels/616186924390023171/731495064508825731/882219386600034376

So i had to go to Internet Options -> Advanced and check the Use TLS 1.2 option.
After that the installation works fine...

[lucasfernog]

Well at least I know I can finish this approach and PR it.

Turn off the safety anti-virus sofware and install successfully

[lucasfernog]

Tauri API_0.1.0_x64.exe.zip

What about this one? This installer doesn't download the MicrosoftEdgeWebview2Setup.exe file, but has it embedded.

[charmfocus]

Tauri API_0.1.0_x64.exe.zip

What about this one? This installer doesn't download the MicrosoftEdgeWebview2Setup.exe file, but has it embedded.

When the antivirus software is not closed, the installation fails Access denied

For what it's worth, this one works without enabling TLS1.2 (which seems to be disabled by default pre-win10).
The app itself still crashes tho. Kinda unrelated to this gh issue, but the error is:

thread 'main' panicked at 'error while building tauri application:
Runtime<CreateWebview<WebView2Error<WindowsError<Error < code: 0x80070057, message: "Wrong Parameter.", win32_error: 87 >>>>>',
src\main.rs:200:6

edit: forgot to add it here, but the crash was transparency related, sorry bout that.

[lucasfernog]

I have no idea what's going on with the antivirus and the webview installer.

[lucasfernog]

The error is happening on this function call: https://docs.rs/webview2-com/latest/webview2_com/Microsoft/Web/WebView2/Win32/struct.ICoreWebView2Controller2.html#method.SetDefaultBackgroundColor
