Body: <p>when I install civicrm-4.7.29-drupal on Drupal-7.56 just using one database for drupal an civicrm the installation runs perfectly without any errors.
  If I use two databases for drupal and civicrm I get the following error message:
  CRM_Core_Exception: Found installation canary. This suggests that something went wrong with tracking installation process. Please post to forum or JIRA. in Civi\Core\InstallationCanary::check() (line 53 of /[my website]/sites/all/modules/civicrm/Civi/Core/InstallationCanary.php).
  What did I do wrong? Or is it a bug?

Comments.Text: Dear Pradeep, many thanks. When I used two new "virgin" databases it worked perfectly. Maybe the problem arose of the fact that I accidentially installed CiviCRM in the drupal database and started all over again.
