Outlook profile "Enterprise Vault" created when 2013 client is installed

We are pushing the Office 2013 suite to our staff.  Desktops are running Windows 7 with a mix of 32 and 64 bit machines.  We have had 2 instances where Outlook 2013 opens with an Enterprise Vault outlook profile.  This profile does not work and a new profile must be created for the user in order to open Outlook. 

We are installing the EV Add-In version 10.0.3.1189. 

We are pushing to several hundred more users in the next few days and would like to be able to address the issue or at least have an explanation.

Thanks.
