Question for someone who has MS Office 2019 installed. I don't have it. Office 2016 created this registry entry: HKEY_CURRENT_USER SOFTWARE\Microsoft\Office\16.0\Word\Options
When 2019 is installed is the above entry used or is this created: HKEY_CURRENT_USER SOFTWARE\Microsoft\Office\19.0\Word\Options
I suspect "16.0" but can't verify and need to assist someone and knowing this will be helpful.
The below thread was helpful but did not address this question specifically: How to detect Office 2019 programmatically?
