If you are encountering an installation failure with DesignShop 12 on a Windows 7 or Windows 8 computer, install Microsoft Edge. Web Runtime 2 from Microsoft Edge is required.
If you receive an error that WebView2 is already installed...
...you'll first need to Uninstall "Microsoft Edge WebView2 Runtime" found in Windows' Control Panel - Programs and Features. Once uninstalled, restart the computer and then install the Web Runtime 2 that you downloaded above.
