Have you checked whether that directory exists? whether your user  
account has permission to create it?

(My guess is that your user account does not have permission to create  
that directory. It looks like you’re storing data in C:\Program Files.  
Don’t do that. Store data in your user directory. That’s why your user  
directory exists.)
