The following PYD files are in C:\Program Files\Reallusion\iClone 7\Bin64\DLLs

In C:\Program Files\Reallusion\iClone 7\Bin64\OpenPlugin only one plugin folder contains several PYD files:

Every other python plugin that I have only contain .PY files in their folders. Since none of the plugins are installed as such, they only require that the user copy the file folder to C:\Program Files\Reallusion\iClone 7\Bin64\OpenPlugin, there's never been a requirement to place anything in the DLL folder. Everything in there is added during the main installation of iClone and never gets touched again by the user.
