title: Windows 8.1 Pro MinGW Gfortran Command Prompt 'not recognized command' error
body: <blockquote>
  <p>C:\Users\redacted\Documents\redacted&gt;gfortran hibrac.f -o hibrac.exe</p>
  <p>'gfortran' is not recognized as an internal or external command,
  operable program or batch file.</p>
  </blockquote>
  <p><a href="https://gcc.gnu.org/wiki/GFortranBinariesWindows" rel="nofollow noreferrer">https://gcc.gnu.org/wiki/GFortranBinariesWindows</a> seems similar to my problem: gfortran.exe is in C:\Windows\MinGW\bin -- except the solution appears not to apply to Windows 8.1 Pro:</p>
  <blockquote>
  <p>Right click on My Computer, Properties, Advanced Tab, Environment Variables.</p>
  </blockquote>
  <p>Instead I tried: Right click on 'This PC' within File Explorer, Properties, Advanced system settings, Advanced Tab -- and I cannot find an equivalent-looking section that allows me to proceed with the advised solution.</p>
  <p>As background information:</p>
  <p>I had installed MinGW Installation Manager which installed mingw32-gcc-fortran (together with mingw32-base, -gcc-g++, and -gcc-objc) in the recommended C:\Windows\MinGW folder, without any apparent error message.</p>
  <p>Isn't it acceptable -- standard practice -- to have one's code in a folder separate from this MinGW folder? i.e. a subdirectory of my Users\account rather than a subdirectory of MinGW. This isn't the problem, is it? What do I need to do to get it to recognize the gfortran.exe, or call it correctly?</p>
  <p>Please tell me what to do to get it working. If it's relevant, I have a Japanese computer with an English language pack installed (it seems to have some gaps, such as some text in the Settings charm or startup/shutdown text being in Japanese).</p>
