I don’t know the location for DVD installation. I live in Australia, we don’t get the DVD version here. and I don’t have a DVD drive in my PC either. I haven’t had a DVD drive in my computer for the last 5 years. I know where the sim is installed for the Steam version or the Windows Store version. And it usually shows up on the desktop directly.
When you install the DVD version, does it ask you if you want to create a shortcut on the desktop? And you are on the latest version of Windows 10 (20H2), right?
