In order to use the TRAIL tool, follow these instructions and obtain an activation code which will enable you to use a 30-day free trial.
1. Download the tool (The TRAIL tool download capability will be restored shortly. Please contact us if you wish to get a copy of the tool.)
2. Making sure your copy of ArcGIS is closed, double click the tool and select “Install Add-In”. The TRAIL tool will automatically install into your copy of ArcGIS.
3. Open up ArcGIS and obtain your user id. This is a number unique to your computer which will be used in generating your activation code. If the TRAIL toolbar doesn’t show up automatically click “Customize -> Toolbars -> TRAIL Toolbar”. From there click “TRAIL -> Help -> Register Product”.

Note: This version of the Trail tool works in ArcGIS 10.0 and 10.1 .
