Unable to compile program

Hi,
am a newbie, get everything setup for dual-mc33926-motor-shield on arduino.
above file is in the arduino library
but cannot compile, program show following error on

Demo.ino:1:36: error: DualMC33926MotorShield.h: No such file or directory
Demo:3: error: ‘DualMC33926MotorShield’ does not name a type
Demo.ino: In function ‘void stopIfFault()’:
Demo:7: error: ‘md’ was not declared in this scope
Demo.ino: In function ‘void setup()’:
Demo:18: error: ‘md’ was not declared in this scope
Demo.ino: In function ‘void loop()’:
Demo:25: error: ‘md’ was not declared in this scope
Demo:37: error: ‘md’ was not declared in this scope
Demo:49: error: ‘md’ was not declared in this scope
Demo:61: error: ‘md’ was not declared in this scope
Demo:73: error: ‘md’ was not declared in this scope
Demo:85: error: ‘md’ was not declared in this scope

This error means that the library is not properly installed into the “libraries” folder of your Arduino set-up.
Or it means that you spelled the include file name differently from the actual library, perhaps.

thanks got it
