    What does this mean? Does the 64 bit machine use 32 bit arithmetic for such a project? thanks

      You can run 32 bit on 32 or 64 bit machine. However 64 bit has to run on a 64 bit machine ONLY!

          Are you certain you targeted 64 bits when building on your 64bits machine ?

          Watched code never compiles.

              Please start providing some clear facts about your tools, their switch settings, your app, the kind of calculations you are doing, what parts run fine, what parts don't, how the results are different from what you want; show us a code sample (with variable declaration!) and some relevant results (twice: good and bad). i.e. stop saying "it doesn't work" :)

              Please use <PRE> tags for code snippets, they preserve indentation, and improve readability.
