MSP430G2553.h Header File

As a brand new user, I am working through the Launchpad Student Guide that instructs me to look for the MSP430G2553.h file on my hard drive. The file is not there. Anywhere else that I can get a hold of it and put it on my hard drive?

And I assume that one of the installation programs would have installed this file on the hard drive. Where would it have done so?

Thanks,

Earle
