Hello. My Professor sent me a link to the Autodesk page where students can download Autodesk Inventor Professional 2012 (pretty sure that's the version the campus uses, the installation background and boot screen match). I received the product keys and downloaded the 3GB install file without incident, but I get an error when trying to install. It skips straight to 18/19 complete and gives returns errors (all check marks in component boxes turn into red x's). I deselected all options except the top one and it seems to be installing. Do I need those other components for the program to function properly? I have attached the error report that was generated if that helps in any way.
