I'm using the Composer Windows installer and it brings me to this window,
There is nothing in the dropdown, but I'm not sure where to pick the correct command-line PHP. Should I direct it to the php.exe in XAMPP folder?
If you are using wampp do this:
Click the browser button.
Then select your file path like following path.
(C:\wamp\bin\php\php5.4.12\php.exe)
If you are using xampp do this:
Click the browser button.
Then select your file path like the following path.
(C:/xampp/php/php.exe)
