drupal is not working on localhost

Hello,

this is the first time that i use drupal. I have this backup from the hosting server with all files and mysql dump. I have to test it on my localhost ( wamp) but after restore files and DB i have this error trying to lunch the site ( http://localhost/mysite/ ):

Fatal error: require_once(): Failed opening required 'C:\xampp\htdocs\vitrum/includes/actions.inc' (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs\vitrum\includes\common.inc on line 5152

What i have done:

1) restored all files from backup
2) Imported mysql dump
3) Changed data into settings.php ( sites/default )

What i don't know:

1) Drupal version

Xampp version: 1.8.3
[PHP: 5.5.30]

What can i do? There are some others files or something to setup?

Thanks!
