Hi All,<br>
<br>
I was trying to access some GRASS 7 functions through the Processing toolbox<br>
in QGIS 2.4 (32 bit), but none work (see error message below). The other<br>
packages I've tied in the Processing toolbox seem to work fine. My machine<br>
is running Win7 64 bit. I've gotten this with versions installed from both<br>
OSGEO4W and the basic QGIS installer. I've tried suggestions recommended in<br>
this bug report thread with no success: <a href="http://hub.qgis.org/issues/10714" target="_blank">http://hub.qgis.org/issues/10714</a><br>
<br>
Any suggestions or useful interpretations in of the error message?<br>
<br>
Thanks!<br>
Mike<br>
