Arduino Simulink Connection Error "Failed to generate all binary outputs Error"

While trying simple led blink example of arduino, I am getting this error. Matlab is already under folder so it can not be space problem in the path. Can anyone help me to fix this?

I am facing the same problem and have spent 3 days but could not solve the issue. Please provide, if there is any solution. (I am using MATLAB R2017b)

[Naveed Mazhar]

I have resolved the issue. There was a space in the name of directory in which I had placed my simulink file. I removed that space and it worked. Also, I reinstalled my arduino files in the folder: C:\ProgramData\MATLAB\SupportPackages\R2017b\toolbox\target\supportpackages

Good Luck

Can I ask you please Sir Naveed how did you checked that there s a space in your directory and how did you deleted it ?? am really grateful if you answer me, cause am struck in here 5 days ago :/

Sorry by Space I dont mean memory/volume. I mean spaces <> in two words of a folder name in directory path... Remove spaces and hopefully issue would be resolved.
