Error installing Ultimate for first time

Hi, can anyone help with this error, i cant seem to track the solution- Any help would be great.

I went over the installation and can't seem to find out the problem.

Warning: require(fn.addons.php) [function.require]: failed to open stream: No such file or directory in -----l/install/app/Installer/App.php on line 149

Fatal error: require() [function.require]: Failed opening required 'fn.addons.php' (include_path='/home/r22r44/public_html/app/lib/pear/.:/usr/lib/php:/usr/local/lib/php') in -----/install/app/Installer/App.php on line 149

Check to see if /functions/fn.addons.php exists.

CAnt find it anywhere, not even in the zip file

In apps/functions/fn.addons.php

it is in that file
