Deploying Outlook to Install Citrix XenApp

I created an Outlook add-in. It does nothing special, just adds a menu with one menu item. I completed the tutorial on creating the installer from http://blogs.msdn.com/b/mcsuksoldev/archive/2010/10/01/building-and-deploying-an-outlook-2010-add-in-part-2-of -2.aspx .

It installs and works correctly during normal installation of the Windows desktop, but I cannot figure out how to do this in the Citrix XenApp environment. I can install it using the installer in the same profile where Outlook was successfully installed. But when Outlook is running, it is located in the "Inactive Applications" section, when I view it from the "Trust Center" menu, and it will not be normally activated. If I open the "Manage COM Add-Ons" menu, it will display "Download at Startup" as my load add. If I try to activate it manually from this menu, nothing will happen, and if I open it again, Load Behavior will change to "Not Loaded". Failed to initialize Managed Add-in boot loader.

Has anyone come across this or anything similar before? Thanks in advance.

If it installs but is inactive, it probably throws an exception at startup.

I would wrap all your startup code (ThisAddIn_Startup inside your ThisAddIn.cs) inside try {} catch {} and log all errors on disk so that you can understand why Outlook disables your addin.

You tried to set the environment variable VSTO_SUPPRESSDISPLAYALERTS to find out if you can get a forecast to give you more information?

(By the way, I discovered outlook VSTO to be flaky. Sometimes they just refuse to install and work.)
