I&#39;ve just downloaded and installed gretl, but the graphs don&#39;t work. I&#39;ve uninstalled and reinstalled but it still doesn&#39;t work. When I try to get a graph, it opens a gnuplot window and gives an error message: &quot;Invalid byte sequence in conversion input&quot;. In fact the message is &quot;sequência de bytes inválida na entrada de conversão&quot; since I am runnig a Portuguese-Brazilian version.<br>
<br>Well, I also noticed that gretl uses a directory in &quot;Documents and Settings/Application Data&quot; for temp files. When I ask for any graph, it generates the .PNG temp file and gives the error above. When I click the &quot;ok&quot; button, the png and other temp files are deleted.<br>
<br>Any ideas?<br><br>Thanks<br>Arthur<br>
