3DS Max 2019 and IPACS Plugin not working

  • I can't get the 3DS Max plugin to work with Max 2019. I'm using the 2017 version, but often older plugins work with later versions.


    I've tried copying the plugin to the Max plugins folder and separately tried referencing the correct SDK folder directly.

    The only thing slightly non-standard about my insatllation is that it's installed in D:\Program Files


    I get the following error.

    (It's Windows 10, 64 bit)
