Unable to install Composer on Windows to work with Scriptcase

I had to do a fresh install of Scriptcase. Everything works just fine now. Next I wanted to install Composer. I recived the following message after executing the install (composer-setup.exe):

The PHP exe file you specified did not run correctly:
D:\Development\NetMake\Scriptcase\components\php\php.exe

The php.ini used by your command-line PHP is: D:\Development\NetMake\Scriptcase\components\php\php.ini

A setting in your php.ini could be causing the problem: Either the ‘extension_dir’ value is incorrect or the dll does not exist.

Program Output:
PHP Warning: PHP Startup: Unable to load dynamic library ‘oci8_12c’ (tried: D:/Development/NetMake/Scriptcase/components/php\ext\oci8_12c (The specified module could not be found.), D:/Development/NetMake/Scriptcase/components/php\ext\php_oci8_12c.dll (The specified module could not be found.)) in Unknown on line 0

Any ideas. Thank you for the assistance.
