Error in MinGW compiler

I am trying to use MinGW but I'm receving this error:

Error using mex
'C:\ProgramData\MATLAB\SupportPackages\R2019a\3P.instrset\mingw_w64.instrset\bin\gcc' is not recognized
as an internal or external command,
operable program or batch file.

I don't know how to fix this.

I would reinstall and then do another

mex -setup C

I already reinstalled and gives the same problem.

We can only guess:

See whether gcc.exe is located at

'C:\ProgramData\MATLAB\SupportPackages\R2019a\3P.instrset\mingw_w64.instrset\bin\'
