Hi Zuheir
Take a look at the instructions here (http://docs.moodle.org/en/Installing_AMP#Windows). Two steps are needed:
- Run set_xampp.bat. Apache, etc will install.
- Load http://localhost in your browser. Moodle will then install.
Details of the moodle install part are here (http://docs.moodle.org/en/Installing_Moodle#Go_to_the_admin_page_to_continue_configuration).
