Hi Dison,
could you please send the installation logs. These are in the installjammer registry directory, which may be hidden and is found under program files or program files (x86).
Your licensing options are outlined here. For Stellaris this means either a purchased license or the license that is free to use with the xds100/stellaris icdi.
