I am using QGIS Brighton 2.6.1. Today I have installed Grass GIS 7.0.0 RC2 to try its topology functions in QGIS.
I have activated the provider, set the paths, but everytime I try to use any Grass GIS 7 command, I get the "Missing dependency.This algorithm cannot be run :-(" error. Grass in standalone is working just fine. Windows 7 64bit user as it stands in the title.
