So, i success to install Drupal 7 Acquia the first time i did it.
I had to remove all and remake the installation
But now when i launch the installation, profile and language settings are auto-loaded and i can't change them anymore :
http://localhost:8080/acquia-drupal-7.22.21/install.php?profile=acquia&locale=en
I past so many hours to search a solution, without success. I know i can translate after the installation but it's not that i want to do. Thanks for answers
