Unable to set the interactive property of the Application class

Thanks for the kb article Doc. I took a look at the registry entries in my user profile on the terminal server and then logged in as the other users and found there was a difference in the BIGenerator entry. I applied this setting and that took care of the problem.

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Excel\Addins\BIGenerator]
"Description"="BI Generator"
"LoadBehavior"=dword:00000003
"FriendlyName"="BI Generator"
"CommandLineSafe"=dword:00000001
"Manifest"="C:\\Program Files (x86)\\Common Files\\\\BIGenerator\\AlchemexWizard.vsto|vstolocal"
