I'm working on a modified installation of Voltage SecureMail for Office 2013. While it is unsupported, Voltage will run in Office 2013 and in Windows 8. I had to use Orca to remove the prerequisite checks for O/S and Office version, which allowed the program to install.
However, now the Outlook add-in is not loading, and Outlook will not let me add it manually.
The current solution we have is to install Office 2010 first, then install Voltage, then upgrade to Office 2013. I am hoping to create a solution whereby it can be installed directly into Office 2013.
Any ideas for forcing Outlook to accept the add-in?
