Windows has official rules for this.  Users are no longer allowed to add
random files to an application's directory in "/Program Files/Appname".
Permissions are set to prevent it and that directory is virtualized to
prevent it.
 The exception is - Applications can install their own bundled plugins in
"/Program Files/Appname" at install time only (because the installer has
elevated privilege).

User installed plugins go in CSIDL_PROGRAM_FILES_COMMON , e.g. typically
"C:\Program Files\Common Files\LADSPA Plugins..."
