Legacy LBT THERM components don’t currently work with Rh7
THERM is closed source and a good bit harder to work with than E+/OS etc.
I personally; if you have a R7 license; than on the McNeel website you can get access to R6 via your R7 license:
That’s is what I do personally.
I hate THERM… but when I have to THERM: I do it in R6 via the legacy LBT kit, but right now: Doesn’t work with R7.
