The extension was orignally programmed for use with ArcGIS 9.0. However, ESRI made several structural changes to ArcGIS between versions 9.0 and 9.2. We have released a version to account for this, which can be found from the download link on the main page.

Should you happen to have a more recent release of ArcGIS than 9.2, and you find that the 9.2 installer does not work, you can still use the extension. ESRI releases a development kit with ArcGIS, which plugs into Visual Studio .NET. If you have the corresponding version of .NET, simply install the developer's kit from ESRI, and download the source code for the extension.

When you open the project in .NET, go to File -> Open -> Convert. There should be an option for "ArcGIS Code Converter." This ESRI supplied converter will convert our code to the newest version, taking into account internal structural changes by ESRI. More information on this converter and changes to ArcGIS are available from ESRI.

Once you have converted the code, recompile the project and use the created installer to install the extension. It should work now. If not, please email Thomas Bien at bien.thomas@alumni.unc.edu, and we will try to investigate what is wrong.
