The Outlook add-in is supported on any version of Office/Outlook from 2003 up, the installed version of Outlook needs to be 32 bit. We do not support 64 bit versions of Outlook.

The Windows OS can be 32 bit or 64 bit.

Due to changes in components shipped with Office 2013, some manual intervention may be required following the standard setup process. Contact the OpenCRM support team for assistance in this instance.

Installation of the Outlook Add-in on Virtual machines and Parallels for Mac should work, but is not officially supported.

We do not support 64bit Office of any version.

I have installed the Add-in with the Administrator credentials but it has not installed?

When installing the Outlook Add-in the account being used to install this needs to be temporarily changed to an Administrator.

Attempting to install this onto a standard user with the Administrator credentials will not install it onto the current user logged into the machine.
