How do determine whether the user using enterprise or business using the registry key?

[Manh Duong]

I'm in charge of patching 500 machines currently using Nitro Pro 13 with 3 different editions. I can know between NLS vs business and enterprise using the registry key \HKEY_LOCAL_MACHINE\SOFTWARE\Nitro\Pro\13\settings ~ InstallSource. But not the case for Business vs Enterprise, the InstallSource of those 2 products is vlp

So I want to ask,  How do determine whether the user using enterprise or business using the registry key? Thank you!
