I have tried multiple fresh installs of Julio from zip and gz files on Acquia Dev Desktop (latest release).
This is the installation error message:
Fatal error: require_once() [function.require]: Failed opening required '/feature_set.admin.inc' (include_path='.;C:\Program Files (x86)\acquia-drupal\common\pear') in C:\Users\M\Desktop\julio-7.x-1.x-dev-core\julio-7.x-1.x-dev\profiles\julio\julio.profile on line 106
This happens right after you chose a language (English) and click "save and continue" button.
Same error message occurs during a fresh install under different directories as well.
