Do this:

  • Start Windows Control Panel.
  • Navigate to System and Security > System > Advanced system settings.
  • Click the "Advanced" tab.
  • Click the "Environment variables..." button.
  • In the "System Variables" list, you should see "GCC EXEC PREFIX". Click on it.
  • Click the "Delete" button.
  • Click the "OK" button.

The error should now be fixed.
