Can some please help me

My computer crashed to the point where I had to go and buy a new one (had it for 7 years), well any how it had windows xp -- I had no problems working with it. Now I have windows Vista  Now when I installed my Poser 7 it installed fine -- then I installed all the 4.2 morphs, now I get this prompt. Can some one help me.  Poser Executable File has Stopped Working --- where are the Poser Executable File located  at?
 

Thank you
