I would like to try Target for ArcGIS to figure out its abilities and specifications to compare with other geological software like Gemcom. I have downloaded free Target for ArcGIS version 3.2, but it isn't installing on ArcGIS 10.2. It shows me that I need to install other versions of this extension first or maybe I should change my Windows Installer. My Windows Installer is working properly. Could you please advise me on how and where I could download and install Target for ArcGIS with its extensions including Target, Voxel properly?
