This tool will is only available for Windows (unavailiable for UNIX).
The Update License tool is installed during the 8.1 License Manager installation. Use this tool to add and update license keycodes on your license server.
For instance, your original purchase included keycodes for ArcInfo, ArcEditor and ArcView floating, but no extension keycodes. You install the 8.1 license manager using this license file. Later, you purchase Spatial Analyst, Geostatistical Analyst and 3D Analyst. You receive a new license file containing only these keycodes. The Update License tool allows you to easily add these new keycodes to your existing license manager.
If you received the file via email, save it as a .txt file before opening it. Do NOT save this file in C:\Program Files\ESRI\License.
The hardware key number in the file needs to match the hardware key plugged into your license manager server.
Open the Update License Utility located at Start > Programs > ArcGIS > License Manager > Update License Utility. Follow the instructions on the Update License Utility dialogs.
After the Update License Utility makes the license changes it will perform a reread of your updated license file. Your license manager will be ready for use.
This tool will NOT shut down your license manager service. It will import the new features and perform a LMREREAD.
You do NOT need to manually Stop, Restart, or reboot your license manager.
