I'm using QGIS 2.6.1 and i've been having problems using the polygonize function.
I keep getting a "DLL load failed" import error. I've searched older threads which unfortunately weren't able to help. I tried resetting the GDAL executable path to
C:/OSGeo4W/bin/osgPlugins-3.0.0, and the python path to:
C:/Program Files/QGIS Brighton/apps/Python27/Lib/site-packages/osgeo.
I don't get this problem when I try to use other functions (Rasterize or Extraction-Contour, for example). So i'm not sure whether it's a problem with the path or something else. Any ideas?
