Browser Requirements for the Web Client
To install Unity, you must click the Unity link from either an EDGE or Internet Explorer browser, and be sure that hccanet.org is in the browser’s trusted sites.

There are two versions of Unity available, one that defaults to Outlook for email, and one for Gmail. Simply click the link from IE to begin the download/install:

Unity Client for users with Outlook for email

Unity Client for users with Gmail for email

To change the version of Unity you currently have, it is highly recommended that you uninstall the old version first.  Beyond that, while it is not required, we also recommend that you do a complete uninstall. This will likely require help from your technical administrator. Complete Uninstall Instructions
