I followed the guide here: http://tremmapping.pbwiki.com/Q3map2Toolz
I downloaded the file, extracted it, and it doesnt have the Q3Map2Toolz_setup as the guide says it should
use q3map2build not toolz
The file is .exe as you download it from fileplanet. You probably downloaded the latest q3map2 version and not q3map2toolz. And toolz has a dandy mapacker which you'll like thorn.
