Windows 7 Enterprise
Installed Dev Desktop and tried to download my Acquia Cloud site. Didn't work.
Created a new Drupal 8 site in Dev Desktop. Tried downloading D8 modules and themes via Drush and the update panel. Didn't work.
Getting the following errors on the Drush terminal window:
simplexml_loadfile(): I/O warning : failed to load external entity
Failed to get available update data from https://updates.drupal.org/release-history/business/8.x
Could not download requested project(s)
Oh, I see you are having mollom problems too. Welcome to my world with Acquia!
