Fatal error during the installation of Drupal 7

When installing Drupal 7.22 on Windows 7, I encountered this issue... this is towards the end
http://drupal7/install.php?profile=standard&locale=en - this is the address, and this is what appeared in the window (the site links were not provided)....
Fatal error: Call to undefined function field_attach_load() in Z:\home\drupal7\www\includes\entity.inc on line 321
