Issue determining .NET version by reading registry

[This article](https://docs.microsoft.com/en-us/dotnet/framework/migration-guide/how-to-determine-which-versions-are-installed) describes how to determine which versions of .NET are installed on a Windows machine.

We have a Windows Server 2019 machine which has .NET Framework 4.8 installed, having previously had 4.7.2 installed. The following keys exist:

`HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full`
The `Release` DWORD contains the value 461814, corresponding to the .NET Framework 4.7.2.

`HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full\1033`
The `Release` DWORD contains the value 528040, corresponding to the .NET Framework 4.8.

So there seems to be more to this than what's outlined in the article. Should we be checking both locations? 1033 seems to be a locale ID, so could the number differ for different locales?
