During installation, most UM-GIS software packages will create a shortcut on the desktop or in the Start Menu -- Programs folder.  Some common software problems are listed below by package.

ArcGIS Floating (ArcMap, ArcCatalog)
ArcGIS Floating requires a network connection to the campus license manager.  To set or modify your computer's ESRI license manager, please click here.

ArcGIS Single Use (ArcMap, ArcCatalog)
At the end of the installation, ArcGIS should prompt you to register ArcEditor and any extensions.  These codes are available in the Installation Instructions link under the ArcEditor software download link.  If you cancelled out of the registration, you will need to use the ESRI Desktop Administrator to re-open the registration window before you will be able to use ArcGIS.  Go to Start Menu -- Programs -- ArcGIS -- Desktop Administrator.  On the left, select the folder "Register Single Use and Extensions".  Click on the "Register Now..." button.  For the Registration Method, be sure to use the "Register now using the Internet (Recommended)" option, which is the default.

ArcView GIS (v 3.X)
The first time you run ArcView GIS after installation or upgrade, you will be required to register the following information:
Name:  <your name>
Organization:  University of Michigan
Registration code:  <UM affiliates should email gis.help for this code>
CSCAR currently offers ESRI-Authorized training workshops in ArcView GIS.  See the CSCAR Workshops page for more information.
