    Yes we need a little more information if we can help you.  Do you know if you have a 64bit processor?

    If you do not have a 64 bit processor, you know you have 32bit version. Click start, run and type dxdiag. On the main page of the popup window, you will see the system specs. if the OS is 64bit, it will say like Windows XP x64 or something.
