[GRASS-user] using orthortectification tool to orthorectify SPOT-5 images

Greetings
I will receive a few SPOT-5 and I will need to Orthorectify them. First of all, how can I use i.ortho.photo in WIndows (the menu entry is disabled)?
Second, does it already include a DEM product or I should download one?
If I need to download, what free DEM do you suggest?
Thanks
Luis

i.ortho.photo is for aerial photographs, not satellite images. Currently it is not possible to do orthorectification of satellite images in GRASS.
