While trying to use ArcPress for ArcInfo Workstation by way of the command line interface on an MS-DOS prompt, the following error is returned:
"ArcPress Not Licensed!"
Problems may also occur while trying to print or export with ArcPress through the ArcInfo Workstation Print dialog box; the dialog box may disappear after clicking OK to print or export with ArcPress.
This is a known issue with ArcInfo 9.1.
Neither ArcPress for ArcGIS Desktop nor ArcPress for ArcInfo on UNIX platforms are affected. This patch is not required for ArcPress, ArcGIS Desktop, ArcPress, or ArcInfo on any UNIX platform.
