Hi,
I accessed one of the GIS PC's and uninstalled gINT, I then installed gINT version 8.30.03.187 as provided.
It still did not install a gINT toolbar into ArcGIS.
I did follow the second procedure you suggested and copied the attached file to the C:\Program Files\Common Files\ArcGIS\Desktop10.0\Configuration\CATID folder.
After that I was then able to turn on the extension and add the toolbar.
Thanks
