Hi Nguyen,
This error indicates that Bikesim was unable to communicate with the installed MATLAB on your system. Bikesim communicates with MATLAB/Simulink using COM Interface. You need to register the MATLAB version you want to use with Bikesim with the COM service, and then Bikesim can communicate with it.
First of all make sure that you have selected the MATLAB version you want to use with Bikesim, by going to Tools > Select MATLAB Version.
To register MATLAB with COM service:
- Right click on the MATLAB shortcut and open Properties.
- In the Target box, append -regserver
- Click OK.
