Error: 'g++' could not be spawned. Is it installed and on your path?

While trying to run c++ in Atom editor.

I installed 'gpp compiler' in Atom Editor File==>Settings==>Packages==>'gpp-compiler' I also installed gcc-core-9.2.0-1-mingw32-bin and provided it's \bin path in PATH variable. Still I am getting this error while running a simple C++ code.

Error: 'g++' could not be spawned. Is it installed and on your path?

Any help!
