This is the BIG issue introduced with Vista.
Either turn off 
      User Account Control, or run the program as Administrator.
I think 
      this feature was in XP Pro, but turned off by default, in Vista, it was 
      turned on by default, hence the shock to new users.
Go to [Control 
      Panel]>[User Account] and turn off User Account Control. Albeit, some 
      rogue program could execute an exe file without your authorization. BUT if 
      you turn that off, you are now more in an XP world.
Otherwise, and 
      maybe the safer mode, is to execute the program in Administrator mode, 
      which in effect YOU are, as this is a PC at home, and not in a public 
      office environment.
Do look at Total Commander as an Explorer 
      replacement, and check the boxes under properties to [X] Run as 
      Admin....
Your choice.
All 32 bit applications do go by 
      default to the <x86> program folder on a 64 bit 
      system.
