Can't get Omeka to install correctly

Hi every time I go to [ip]/install/index.html try to install I either get the Omeka Installation Error mod_rewwrite not enabled which it is.
If I try to do [ip]/install/install.php it just displays the php code.
And just going to [ip] results in the php code as well
I've tried playing with ReWriteBase in .htaccess but it doesn't seem to do anything.
Any ideas? Any of my setup you need to see?

I've been going around in circles with mod_rewrite for a couple weeks. Nothing I've done works and contacting my host didn't help.
