Enterprise Vault Outlook Add-in not displaying

Hello,

I am trying to get the EV Outlook Add-in to function. It installs successfully and is Enabled, but does not show up as a menu item in Outlook. I verified that the appropriate registry keys are created because I found some articles about that causing a similar issue. I'm running 64 bit Windows 7 with 32 bit Outlook 2010 and we are running Enterprise Vault Version 10.0.1.1171. The version of the add-in that I have installed (from Programs and Features) shows version 10.0.5267.

I've tried uninstalling/reinstalling many times. Does anyone know how I can get it working?

Thanks for any help!
