I am pretty sure I installed composer correctly, based on the errors I am getting.
Xampp install version xampp-win32-1.8.2-6-VC9-installer.exe
Xampp seems to be working fine.
installed Composer (since I got the error message below, I assume composer is installed fine)
But when I get to the next step in the YII install procedure, I get this error.
Instructions are pretty weak. Am I in the right directory? Where would I find the missing file ? What am I doing wrong ?
