Save-as and Open Dialogue box options. ~ Windows style vs Adobe style

I have two identical machines, that are running CCv6 software. On one machine I have Libraries as an option in my save as box and in the other it's using the Adobe pre-set options. I have not edited the registry file. I am not running any aftermarket plug-ins. There must be a dialoge box somwehere, but I can't find it. Help it's making me crazy trying to drill down to my save files.
