Installing px4 suit for the Matlab software

Hello,
I follow this PDF to add the pixhawk suit on my Matlab/Simulink : Simulink_Pixhawk_Support_v2.1.pdf (3.0 MB)
But when I install the file called “Pixhawk-R2016a_v2.1_win64-Install.exe”, just after setting the Cmake configuration, Matlab send me this message and I can’t continue the installation :


I thank you in advance for your answer.
Best regards,

Fred,
Have you got the necessary “Embedded Coder” product installed?
Did you download the package from MathWorks’ website?
Most of these support questions concerning this Pilot Support Package (PSP) should be directed to MathWorks technical support (https://www.mathworks.com/support/).
