Installer Redirect Loop

Dolphin installer keeps redirecting for some odd reason. When I visit it, it keeps on redirecting until eventually the URL looks like:

http://www.example.com/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/install/index.php

How do I stop it from doing this so I can install the script?

It seems there is some problem with your .htaccess redirect rules. Just rename the .htaccess to .htaccess.old and try again.

Now the installer says:

"Notice: Use of undefined constant BX_DIRECTORY_PATH_INC - assumed 'BX_DIRECTORY_PATH_INC' in /var/www/index.php on line 41 Warning: require_once(BX_DIRECTORY_PATH_INCdesign.inc.php): failed to open stream: No such file or directory in /var/www/index.php on line 41 Fatal error: require_once(): Failed opening required 'BX_DIRECTORY_PATH_INCdesign.inc.php' (include_path='.:/usr/lib/php-5.3.6/php') in /var/www/index.php on line 41"
