Hello,

In answer to your question, "I assume, the main executable is different and the license key that identifies the edition?
".

Yes, they are different, so do you recommend unique Product/Upgrade GUIDs or identical GUIDs?

I have searched the documentation and can't find any explanation or suggestions on when to use unique GUIDs and when to share GUIDs.

Can you give us a guidline as to when unique GUIDs are a good idea and when shared GUIDs are a good idea?
