Yeah, it's a common issue with Bethesda games. They do not recognize integrated graphics cores. You'll need to do an old trick dating back to Oblivion to get the game running. You need to insert a d3d9.dll file into the Fallout: New Vegas directory.http://www.oldblivion.com/sm/index.php?topic=6928.0
This trick should work for Skyrim as well.
