Hi kaanfaruk,
According to the official document, the version of RegistryView applicable to .NET Framework ranges from 4.0 to 4.8.
So you need to change your target framework.
Then you can follow this document to determine which .NET Framework versions are installed.
And you need to note that the version of .NET Framework (4.5 and later) installed on a machine is listed in the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full.
Each version of .NET Framework from 1.1 to 4.0 is listed as a subkey at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP.
So if the Full subkey is missing, then .NET Framework 4.5 or above isn't installed.
I made a test with the code in the link and it worked fine.
The result:
