title: VSTO Excel add-in not loading on terminal server
body: <p>My configuration is windows server 2003 (i'm logged in with admin privileges), office 2003, vtso runtime 2005 se. After installing my addin, all registry keys are in the correct locations and I have given fulltrust to my assembly using caspol.exe. My addin is a application level addin. </p>
  
  <p>When I run excel with regmon and filemon running I can see that excel reads the registry keys of my addin, but I do not see the AddinLoader.dll being loaded in filemon. I get no errors from vsto since it doesn't appear the runtime is even starting up. I've read almost all of the vsto doco on msdn particularly the application addin architecture and vsto runtime overview as well as various other articles and discussions on the topic. I still can't figure out why the runtime won't load on the terminal server.</p>
  
  <p>When installing this on an XP machine it all works fine and my addin gets loaded every time.</p>
  
  <p>Anyone have any idea what might be preventing the vsto runtime from loading?</p>
