Do not speak English well. I do not have enough explanation.  The suspicious part is the MinGW program I checked the configuration of the rest of the files except MinGW. MinGW install program name = mingw-get-setup I entered the link and clicked. When I installed it, I showed a different screen. In the last line, have an _install folder. but When I checked _install folder is not exist.  I installed MinGW Program (I added the path as documented.)
