define('IN_PHPBB', true);
$phpbb_root_path='./../../';

Warning: include(./../../extension.inc) [function.include]: failed to open stream: No such file or directory in C:\xampp\htdocs\alice\mods\iai\install.php on line 33

Warning: include() [function.include]: Failed opening './../../extension.inc' for inclusion (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs\alice\mods\iai\install.php on line 33

Notice: Undefined variable: phpEx in C:\xampp\htdocs\alice\mods\iai\install.php on line 34

Answer 1

Does your phpbb install live here "C:\xampp\htdocs\alice\" ?

Should you infact set $phpbb_root_path='../../../';
