I think that my PC might be a 64 bit system, if that is the correct term, rather than 32 bit. I have been looking in system information, but am not quite sure. How can I find out? I want to do this because I am unsure which version of Diskeeper to buy, the basic home edition or the professional edition which supports 64 bit computers. Can anyone advise?
