I have downloaded the installer from the following link https://www.catalog.update.microsoft.com/Search.aspx?q=webview2%20. I ran the installer in admin mode but I am getting Unknown installer error. There is no WebView2 installed already (Verified from the COntrol panel). I tried clearing the %temp% folder too.

WebView 2 version - 109

OS version - Windows_Server-2016

Architecture - 64

    Hi @Ramakrishnan R ,

    This installer you've downloaded is meant for v109 down-level extended support on Win 7, 8, and 8.1 (including Server 2012 R2 which is based on Win 8.1), so you're supposed to install it on one of these platforms and it only serves as an update.

    If you would like to install WebView2, you can visit https://developer.microsoft.com/en-us/microsoft-edge/webview2/.

    This installer worked for me I uploaded it to archive.org: https://archive.org/details/microsoft-edge-web-view-2-runtime-installer-v109.0.1518.78 click "show all files" and download the respective architecture 32bit or 64bit
