xlsopen doesn't work in windows 10 Octave 4.0.3
<p>I am trying to run just the simple code</p>

<pre><code>f = xlsopen('Libro1.xlsx');
</code></pre>

<p>am using octave 4.0.3 in Windows 10, java version 8 update 111 1.8.0_111-b14</p>

<p>From what I have found out so far have:<br>
    already uninstalled it, and installed it again,<br>
    made sure no non ASCII characters are in the path,<br>
    latest java version is installed (not that it matters? supposedly the octave windows installer installs you a version for it) <br>
    loaded both windows and io pkgs <br>
    io version 2.4.3 and windows version 1.2.4<br>
    and am still receiving this error:<br></p>

<p>Have seen various threads, even one that has the exact same message but, either installing java solved it, or another solution was found but not reported on the thread. </p>
