License Manager does not work on 64-bit operating systems


The concurrent use licenses of ArcView, ArcEditor, and ArcInfo require the use of a License Manager application to manage the concurrent licenses. Pre-9.3 versions of the License Manager and associated hardware key used with ESRI's software does not work on a 64-bit machine running Windows XP Professional, Windows 2003 Server, or Windows Vista 64-bit editions.


This is a known limitation.
