A very naive and basic question. I have just downloaded QGIS 2.14.0 and now have 8 new & related icons on my desktop. As a student with no practical GIS work experience, I have worked with ArcGIS 10, and now for it's proclaimed benefits would like to learn to drive QGIS, but am a little confused over which of the choices is appropriate. Also, is one of these icons a similar application to ENVI?
I am using Windows 8.1.
