     The official TMY3 syntax is comma separated. The file you attached
    is tab delimited. Did you download it directly from an NREL site or
    did it get processed (resaved as tab delimited?) along the way?<br>

                TMY3 files downloaded from NREL's site should work fine
              with the demo version. You do have to make sure that you
              are using the TMY3 mode of Type15. When you get the error,
              to what "it" do you refer? Is there an error generated by
              TRNSYS? Is Windows complaining about the file type? Some
              additional specifics about the source of the error and the
              language of the error would help in tracking down its
              cause.<br>
