Bug: ArcGIS License Manager does not work on Microsoft Windows Vista
The ArcGIS License Manager fails to work on the Microsoft Windows Vista operating system.
The version of the FLEXlm License Manager that comes with ArcGIS 9.2 and previous versions (FLEXlm v7.0d) is not supported by Macrovision on Vista.
This bug has been fixed at ArcGIS 9.3. The ArcGIS 9.3 License Manager is fully supported on Microsoft Windows Vista. This updated version supports all ArcGIS 9.x Desktop and ArcInfo Workstation releases and can be downloaded from here:
ArcGIS 9.x License Manager Update
Existing license file and hardware keys can be used with the new License Manager. It is not a requirement to request new licenses or hardware keys.
