You can determine which version of Vista you have by first finding your “Computer” icon by looking either on your Windows™ desktop or by clicking on “Start, then Programs.” Once found right-click on it.  Select “Properties“ from the pop-up menu.  On the next screen you will see a “System” section which will have a line for “System Type”.  This will indicate either 32 bit or 64 bit operating system.
