According to release notes above for 5.4.1 note that Calman control license is required for madTPG support. On the Spectracal website here it list madVR under Enthusiast.
So which is it?
As I understand it control is needed for MadTPG, so you can use the MadTPG patterns as a source, but not MadVR as a display (and use its 3D LUT). This was recently added as before you needed Enthusiast both for MadTPG and MadVR.
So control and above allow MadTPG (source only) and enthusiast and above allow both MadTPG and MadVR (source/patterns and display/3D LUT).
I've been getting random Calman crashes when clicking the disconnect button after a calibration when using a remote MadTPG pattern generator. I am using Windows 10 Tech Preview so this may be the culprit. I'll be upgrading to the latest build, 10041, later today and will report back.
