As of May 15, we are going to officially be discontinuing support for running Fantasy Grounds on Windows XP.
We've already updated the system specifications on both our web site and Steam to Windows 7 officially, though we believe that Windows Vista should continue to work. While the software will not be immediately updated on that date, we will be releasing some software updates soon that will prevent the software from updating any longer on Windows XP.
