Hello all, Reply to myself: downloaded i.histo.match.zip from http://wingrass.fsv.cvut.cz/grass70/addons/ and unziped i.histo.match.py to C:\GRASSGIS70svn\scripts.
Working properly now so I guess something is wrong in the grass instalation procedure.

Installing from menu (gui) doesn't work (see att). Tried manually and although it installs correctly this error message shows when executing it: g.extension ext=i.histo.match Downloading precompiled GRASS Addons <i.histo.match>... Updating metadata file... Installation of <i.histo.match> successfully finished (Mon Mar 04 10:19:01 2013) Command finished (5 sec) Traceback (most recent call last): File "C:\GRASSGIS70svn\etc\gui\wxpython\gui_core\prompt.py", line 271, in OnItemSelected self.cmdDesc = gtask.parse_interface(GetRealCmd(cmd)) File "C:\GRASSGIS70svn\etc\python\grass\script\task.py", line 484, in parse_interface tree = etree.fromstring(get_interface_description(name)) File "C:\GRASSGIS70svn\etc\python\grass\script\task.py", line 461, in get_interface_description "\n\nDetails: %(det)s") % { 'cmd' : cmd, 'det' : decode(cmderr) } grass.script.core .
