Error occurs when I installed first wamp, then IIS. What I did are;

Steps

1. Installed wamp and changed port to 9999
2. Installed IIS and others to run PHP on IIS
3. IIS was ok and wamp shows only localhost:9999, phpMyadmin and project urls are showing blank page.
4. Completely uninstalled both wamp and IIS.

Could not open input file composer.phar Error

After you have installed composer on different directory(not in C: drive),

Step 1: change directory to location where composer.json exist.

eg: D:\xampp\phpMyadmin\composer.json then change to D:\xampp\phpMyadmin

Step 2: command=>php composer.phar install

Here you are!
