title: COM component not activated due to privilege issue
body: <p>We have developed an office add-in. Its working fine with every other system except one. In that particular system when we try to load the app, it fails with a generic error (<em>This app could not be started. Close this dialog to ignore the problem or click "Restart" to try again.</em>). Event viewer has the following details</p>
  
  <p><em>The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID 
  {9BA05972-F6A8-11CF-A442-00A0C90A8F39}
  and APPID 
  {9BA05972-F6A8-11CF-A442-00A0C90A8F39}
  to the user STC\inmchandr SID (S-1-5-21-2779513660-4158667818-3257731910-104078) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.</em></p>
  
  <p>The specified CLSID points to ShellWindows component, which is running with "Interactive User" account. I am unable to change the other security permissions like launching permissions for that component in DCom config. I tried to change the permission for the corresponding registry entry (as suggested in <a href="https://social.technet.microsoft.com/Forums/windowsserver/en-US/3313c6c5-383a-4051-a22a-04452f87642a/the-machinedefault-permission-settings-do-not-grant?forum=sharepointsearch" rel="nofollow">this link</a>) But, nothing worked out.</p>
  
  <p>The winword.exe is running as the same user who logged in. This system and the other systems (where it is working) are in the same network and I tried running gpupdate as well. </p>
  
  <p>(In that problematic system) The same app is loading when we tried to run Word as administrator. The URL used for that taskpane app is launching without any issues from browsers</p>
  
  <p>OS: Windows 8.1
  Processor: 64 bit
  Office: 2013</p>
  
  <p>Could anyone help us out to resolve the issue?</p>
