I am writing an installer for AutoCAD 2012 to install our .Net plugin with the .bundle style of plugin loader. It is my understanding that 2012 does not support the ApplicationPlugins folder under "ProgramData", but only in the "Program Files\AutoDesk\ApplicationPlugins" and the user's "AppData\Roaming\Autodesk\ApplicationPlugins" directories. I want to install my plugin for all users so I assume I need to put it in "Program Files\AutoDesk\ApplicationPlugins". How do I find this at install time? I know that mind is at "c:\Program Files\AutoDesk\ApplicationPlugins", but that location may be different for a different install, right? Is there a registry key or AutoCAD .Net utility that I can leverage to discover that location so I know where to lay down my .bundle bits?
