Installation error

I have tried to install this in our 4.6.8 version (Drupal) and get an error:
CRM_Extension_Exception: Cannot install or enable extension: in /home/crm/domains/(my path)/public_html/sites/all/modules/civicrm/CRM/Admin/Form/Extensions.php on line 195

I installed a fresh download from this repository.

I tried it in a different installation, which is 4.6.9, and that installation worked. The 4.6.9 one is the one I care about anyway. Seems that 4.6.8 had some other problems too.
