The output path on the visual studio 2012 plugin can't be changed when x64 configuration are chosen (both release and debug).
Visual studio 2010 works fine and x86 configuration too.
Whatever I tried on x64 the Output path is overriden by "bin\$(Platform)\$(Configuration)\"
Close on relaunch visual studio don't fix the problem.
