Problem: ArcGIS Desktop 9.x shows availability as 0 when using ArcGIS License Manager 10
When using ArcGIS Desktop 9.x software with the ArcGIS License Manager 10, the availability for the concurrent use products in the Desktop Administrator show 0 (zero) licenses available, even though the software can still be used.
The version number in the licenses for the License Manager 10 cannot be properly resolved by the 9.x Desktop Administrator.
The 9.x Desktop software itself continues to function properly with the License Manager 10.
