How do I get the hacks onto my site?

I have a new question now. Whenever I go to http://marinersmania.com/forums/inst...ck_install.php I get this error:

Warning: opendir(./his_files/): failed to open dir: Invalid argument in C:\Accounts\myusername\wwwRoot\forums\install\hack _install.php on line 46
