Encrypt Message does not work with new Plug-in 7.3

Question

I installed the new Email Security Plug-in 7.3 but now the Encrypt Message button does not work.  It is grayed out and unavailable when I attempt to create a new message. 
I first tried installed 7.3 over the previous version but every time I opened Outlook I received an error message about XML not loading.  I uninstalled the plugin, rebooted and installed it clean and that took care of the XML message.  But I then found the encrypt button issue and have not been able to solve that issue.  This is not isolated to my machine as I have tried installing it on another machine that never had the plug-in installed before.                  

Answer 1

My understanding is that they completely rewrote it, which is probably why an upgrade doesn't work well...
I did get one way of deploying figured out, the stuff on page 3-20 has some errors. 
Here's what I did that works:
     Do a clean install on a machine that doesn't have any plugin installed.
     Copy the C:\Users\All Users\Cisco\Cisco IronPort Email Security Plug-In\Common directory and its contents to a network accsible share, say \\fs1\share\pluginconfig, so you now have \\fs1\share\pluginconfig\Common, etc...
     Copy your BCE_Config_Signed.xml file to the Common folder
     Rename that to config_1.xml
     Edit the CommonEncryptionConfig.xml to have the following XML:
      Now you can push the install with a command line that references the folder (the example on page 3-20 is wrong, no 's' ):
            CiscoIronPortEmailSecurity-7-3-0-102.exe /exenoui /qn UseCustomConfig="\\fs\share\pluginconfig"
       (if you're doing it on the same machine you did the clean install with, you should uninstall it first...)
