title: Will newer versions of an app have the same GUID?
body: <p>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 <em>{3A7F6F75-5A23-4C35-BE3C-D84F6EE8117C}</em> as GUID and <em>3.3.3</em> as version for <em>Oberthur Technologies ID-One Token driver</em>, for instance. Now, I will make inquiries to <em>my server</em> for this software based on its GUID and check for <em>newer versions</em>. Is that ok or <strong>can newer versions have different GUIDs?</strong></p>
