Dear all  
  
I have a 64 bit windows laptop with 64 bit MatLab installed. I want to use Psychtoolbox but apparently it will only run on 32 bit MatLab for windows. Does anybody know if there is a solution for this? This is literally my first day trying to use MatLab so please keep things reasonably simple.  
  
Many thanks  
  
John
