Hi all,<br><br>Finally I got to install the right packages of cygwin (I think) but I&#39;m still not able to run the program properly. Now I get this new error message:<br><br>$ ./xcrysden<br><br>+-----------------------------------------------------------------+<br>

<br></b>I have Xming installed in my computer which I thought would be enough as a X-server. But as I have already said I&#39;m not very familiar with this kind of installing processes so I just keep trying everything I can think of.<br>

<br>This one seems to be a problem of the program itself so I hope you can help me! :)<br><br>Thank you!!<br><br>Lucia<br><br>
