Hello,
Using default value of this registry key I detect the installed Outlook version:
ClassesRoot("Outlook.Application", "", "")
I have tested this key for Outlook 2000, 2002, 2003, 2007, 2010, 2013 and 2016 and it's all OK
For example, for Outlook 2016 the value is: "Microsoft Outlook 16.0 Object Library"
The problem is that for Outlook 2019 and 2021 it's:
"Microsoft Outlook Application"
Or any better way to detect installation AND version of Outlook on a system?
Just in VB.NET without using Office COM objects!

It works on my OS with 2016 by adding the 2016 GUID ({5812C571-53F0-4467-BEFA-0A4F47A9437C}), but I don't have GUIDs for 2019/2021
If you can get them (from registry or from MS people...), the C++ code could be translated into VB
(I did not even find those GUIDs on Google...) -

2022-05-16T21:54:50.05+00:00 omg, didn't recall about the damn C2R version :(
anyone here got Outlook 2016 (and perhaps 2019) C2R installed to check the default value of ClassesRoot("Outlook.Application", "", "") and let me know the result?
