Drupal 8.2.6 install.php path error

Just installed Drupal 8.2.6 to mydomain.tld/drupal ... (aliased, but you get the gist) everything appeared to go well, except the link to complete the installation was incorrect

the link I was offered was mydomain.tld/drupal/install.php - the actual path was mydomain.tld/drupal/core/install.php

Status:
