joomla template quick installation not working

hi, i tried to install like you mentioned with the quick-installation, but when i finished the upload to my server and open the .../index.php -
the installation doesn´t work. It only comes the "congratualtions" window (last page of installation) but all the necessary steps before don´t come.

May you know how to fix it.

PS: i see there are also other customers with the same problem.
