Correct approach to Check for .NET 6 installation

Question

we have an windows forms app built through .NET 6 and during the installation we need to check whether .NET 6 is installed or not. The installation is built through NSIS Installer. I see couple of places where the version can be checked.

1) Registry

   For x64 versions HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\dotnet\Setup\InstalledVersions\x64\sharedfx\Microsoft.WindowsDesktop.App  

  For x86 versions   HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\dotnet\Setup\InstalledVersions\x86\sharedfx\Microsoft.WindowsDesktop.App  

2) .NET installed location - %Programfiles%\dotnet\host\fxr

Are these the right approaches ? Any .NET experts /Microsoft experts can advise on the right approaches?

Answer 1

for the installed .net 6 to work with your code, it must be in path. so you could just execute

dotnet --list-runtimes

and check the results. you could also just deploy self contained applications and not require an install.
