[francescoboccacci at libero.it]

Hi all,
i have a problem in my Windows PC. I try to use a python script that call qgis 
modules.
I tried to do :

>>from qgis.core import *

i receive ImportError: DLL load failed ....

How i have to configure my environment variables to get these modules?
I try to find some solution on web but they aren't work.

Thanks

Francesco
