How to update SW_ROOT

I am taking over a software project from another developer, just trying to get set up.  The last time I did major programming it was for the MC68HC12 family of processors.  It's my first time doing anything with TI products.

I have installed the latest version of the compiler, so it has a different path name, and I'm trying to update variables.  I have SW_ROOT defined below, I think...

But I still have files greyed out.

It's looking for 

TivaWare_C_Series-2.0

Instead of

TivaWare_C_Series-2.2.0.295

I can't figure out where to update the variables.

Thanks...
