Resolution

Version 109 of Microsoft Edge and WebView2 is the last that supports Windows 7 - see https://blogs.windows.com/msedgedev/2022/12/09/microsoft-edge-and-webview2-ending-support-for-windows-7-and-windows-8-8-1/.

But Microsoft has an issue in Evergreen Bootstrapper, so you need to download and install this new file: https://download.eway-crm.com/tools/MicrosoftEdgeWebview2Setup_2.exe
