HDL code Generation creation failed.

Hello,

I got the "HDL code Generation creation failed" error as show in the attached file. I was following the instruction MatLAB tutorial "Basic HDL Code Generation with the Workflow Advisor". The link is "https://www.mathworks.com/help/hdlcoder/examples/basic-hdl-code-generation-with-the-workflow-advisor.html?s_tid=gn_loc_drop".

The command

"coder -hdlcoder -new mlhdlc_sfir" 

before

"ver" 

command above created the error.
