Solver Knitro could not be found

[NicoBravo]

Hello,
I am trying to solve a NLP and I wanna use solver Knitro.
The problem is yalmip could not find knitro. I have added the solver folder knitromatlab whichi includes the necessary files, and also the license. But anytime I try to set up it as the solver, yalmip will tell the error code -3.
I run yalmiptest and only knitro could not be found, like this:

Thus I truly do not know why and I hope you could help me.
Thanks

They have changed the file structure (and call interface) of Knitro, and I have not had the time to update YALMIP for the new version.
