mod_rewrite error on install on 1.5

I'm attempting to do a brand new install of 1.5 and am running into the mod_rewrite error. I've been searching the forums and have checked all the things I've found in them. mod_rewrite is definitely enabled and the .htaccess files are in the root directory and install dir just as they were when they were unzipped.

I don't know much about .htaccess files but I would guess this means that the .htaccess file in the root directory is successful but somehow is failing on the .htaccess in the install directory. Of course I could be way off.
