VS 2019 [RESOLVED] Upgrading Framework 4.8 to 5.0 -- x64 or x86 version?

I would like to upgrade from the Framework 4.8 to 5.0 and would like to know how to find out which platform I should download (32-bit or 64-bit).

I have a Windows 10 Pro O/S (64-bit). I am running Visual Studio Community 2019 version 16.9.4.

I thought this information would be shown in the Help menu ("About Visual Studio") but the Framework platform is not included there.
