Problem: Foreman has issues when its path contains spaces and the default path for Heroku is C:\Program Files(x86)\Heroku.
Fix: Reinstall Heroku and specify C:\Heroku as the path.
Problem: When Heroku is installed in a path other than the default the path to foreman.bat is not added.
Fix: Add C:\Heroku\ruby-1.9.3\bin to PATH environment variable.
