I have down loaded easy mod to my pc
then uploaded it to my server
then when I open the install file I get this,
// Checking phpBB files here allow us to halt installation and warn them with an explanation if the have not upload EM to the correct place

if( !@file_exists($phpbb_root_path . 'extension.inc') )
{
// display error message (obviously we can't use the lang system from this

echo "<b>CRITICAL ERROR:</b> the file 'extension.inc' could not be found. Please, make sure EasyMOD has been uploaded under the admin/mods/easymod/ directory of your phpBB installation.\n";
exit;
}
// Note using require rather than include makes sense, since we can't really proceed if the files are not available.
require($phpbb_root_path . 'extension.inc');
require($phpbb_root_path . 'common.'.$phpEx);
require($phpbb_root_path . 'includes/functions_admin.'.$phpEx);
