Command failure for external command for RiR

. I keep getting this error after trying to run RiR in revit 2018. Please what can be done. Thanks


We have improved the error message for those cases in the last version.
Could you please update your Rhino.Inside copy and test it again.
I also see on your screenshot that you have no Rhino WIP installed on your computer, you can download it from here.

Thanks. It worked but i don’t have a rhino 7 licence. I will work on getting that later.

Rhino 7 WIP uses your Rhino 6 license.
So if you already own a V6 license you will be fine while Rhino is in WIP.
