Will newer versions of an app have the same GUID?

Question

The specific software I'm interested in are the drivers for Athena, Gemalto, Oberthur and SafeNet security tokens, but I also want to know if there's a rule regarding GUID change in app versions. I use Windows Management Instrumentation Command (WMIC) to get {3A7F6F75-5A23-4C35-BE3C-D84F6EE8117C} as GUID and 3.3.3 as version for Oberthur Technologies ID-One Token driver, for instance. Now, I will make inquiries to my server for this software based on its GUID and check for newer versions. Is that ok or can newer versions have different GUIDs?

Answer 1

GUID usually don't change when version change. As long as you keep the same interfaces GUID stay the same.
But Sometimes company decide to change GUID to make clear distinction between 2 versions, or to give an easy possibility to have old and new version at the same time.
