I've been using the undocumented LrUUID namespace for a while now without any problems, however I just had a user report the error:


Could not find namespace: LrUUID


He's using Lr3.4 on Vista


Anybody know in which version of Lightroom this namespace first appeared?


I can't imagine it being an OS thing(?)

    The perils of using undocumented interfaces (of which I'm equally guilty :-<).


    Seems unlikely that this would be dependent on the Windows version (i.e. not available in Vista).  The result of LrUUID (on Windows 7) looks like a Windows GUID:




    Windows GUIDs have been around since at least Windows NT 3.5, I think, when Microsoft collaborated on the DCE standard.

    It does seem like an odd error to experience. Namespaces aren't typically

    something that would change across OSes or even within a major release

    cycle. Would have expected that namespace to have been available since at

    least LR3.2 (but more likely LR3.0) so the upgrade shouldn't really be

    necessary. Lets hope the upgrade fixes the problem for your user.


    Thanks, Matt
