    <p>As seen at [1], xcrysden-1.6.2-linux_x86_64-shared.tar.gz is for
      a Linux distribution [2] that is 64 bit.</p>
    <p>As seen at [3-4], the "Exec format error" might be from trying to
      run a 64 bit executable in an operating system that only runs 32
      bit executables.</p>
    <p>You mentioned using a previous version of XCrySDen.  Have you
      perhaps tried installing XCrySDen with your package manager (e.g.,
      see [5]), tried installing the
      xc-1.5.24-linux_x86-semishared.tar.gz for 32 bit that is on the
      webpage at [1], or tried to compile the xcrysden-1.6.2.tar.gz from
      source [6] to see if one of those works should you be using a
      Linux distribution that is 32 bit?<br>

        Dear Developers,
        <div><br>
        </div>
        <div>Hello,</div>
        <div>I have got a problem running the compiled version of
          xcrysden.</div>
        <div>When running the "xcrysden" command, it got the following
          error:</div>
        <div><font color="#0000ff">~/xcrysden-1.6.2-bin-shared/bin/xcrys:
            Exec format error<br>
          </font></div>
        <div>Any help would be highly appreciated.</div>
        <div>Thanks in advance.</div>
        <div>Regards,</div>
        <div><br>
        </div>
        <div>N.B. I had the previous version of xcrysden before that (I
          can not remember which version of that), however it was
          deleted from my computer.</div>
