I'm a new user trying to use FEFF6l through the "Make FEFF SS Paths" module in SixPack. I downloaded iffefit-1.2.10.exe and installed  everything to default locations (which puts a copy of feff6l.exe inside the fefftemp folder of Sixpack, where I am told it needs to be).
<br><br>I open the &quot;Make FEFF SS Paths&quot; module, enter scattering information and go to run FEFF. I select FEFF6/7 and enter &quot;feff6l&quot; next to FEFF Command (without quotes). I hit Run FEFF - then I get an error:
<br>
-----<br>Error: 3<br>IOError Exception in Tk callback<br>&nbsp; Function: &lt;method PT.runfeff of PT instance at 00A2503C&gt; (type: &lt;type &#39;instance method&#39;&gt;)<br>&nbsp; Args: ()<br>Traceback (innermost last):<br>&nbsp; File &quot;

</a><br>-----<br><br>&nbsp;I&#39;m running Windows XP through
Parallels on an Intel Mac (running Leopard). Other modules of SixPack are running fine. I tried updating SixPack from the&nbsp; SixPack website (as was suggested in the ifeffit install documentation). Does anyone have any ideas?
<br><br>Thank you!!<br>&nbsp;&nbsp; Susan <br>
