| If GEM is configured and installed with default values, there is no need to fill in the last three items on the GEM preferences |
| page. When blank, the plug-in will assume they are in the default location. These three items simply need to be in your path. |

| Please note the smaller help button on this preference page (below ispUI Script label). |
