Help, Code not working

Does anybody know what this error is and possibly how to fix it.

Warning: Failed opening 'GoogleApiSearch.php' for inclusion (include_path='.') in /users/coolfreepage.com/tomshawk/html/modules/GoogleApiSearch/index.php on line 29

Fatal error: Cannot instantiate non-existent class: googleapisearch in /users/coolfreepage.com/tomshawk/html/modules/GoogleApiSearch/index.php on line 43

the person that set it up says it has to do with the way windows does an include statement and he didn't know how to fix it.

This is the line in question and the one before it, that he says needs to be fixed.

ini_set("include_path", ".");
include("GoogleApiSearch.php");
