I've reported this in the feedback tracker here but haven't had any luck so far.

I'm following the pipeline to make MoCap animations with Axis Neuron and iClone 7 with the Perception Neuron plugin.
Axis Neuron is working correctly and is configured according to the video here: https://www.youtube.com/watch?v=H0tTVlNx4S8
iClone 7 seems to work fine at first. I open the Perception Neuron plugin and identify the relevant character and click connect. It seems to be fine. However, when I click "preview" or "record" it hangs for a second, then crashes to desktop.

I get the following debug message: "Unhandled exception at 0x0000000064CA1233 (Qt5Core.dll) in iClone.exe: 0xC0000005: Access violation writing location 0x00007FF7F4E402D0."I'd be grateful for any ideas on how to fix this.
