OK. Please check that r.roughness.vector.bat is present in:

C:\Users\xy\AppData\Roaming\GRASS7\addons\bin, or
C:\Program Files\GRASS GIS 7.1.svn\bin

Possibly run

debug(parseGRASS)
parseGRASS("r.roughness.vector")

and check that its *.bat file is present in WN_bat under debugging. I'll 
try it too.

The revisions add *.bat from local addons to the global list of *.bat, but 
something may have got lost - it worked for me for r.basin.
