Error: PHP is not running

Wassup!

I’m kinda new at this whole WordPress using, I’ve read all about what there is to do in order to install and start with the whole making of the website but here I am still at the first step.

I’m using a webhost from Mexico (it’s called “Triara”) I changed my platform to Unix, so it could read and write php. I downloaded the latest version of wordpress and uploaded into my ftp uploader.

The problem is when I open my “install.php” file on the browser, doesn’t matter what I do it says “Error: PHP is not running,
WordPress requires that your web server is running PHP. Your server does not have PHP installed, or PHP is turned off.”

I’m about to shoot myself in the face, cuz even the people at support from the website can’t tell me what’s wrong.

If you could help me I’d be more than thankful.

HELP!!! Thanks! 🙂
