Why does my open cart 1.5.4 version not have a live update option in System settings?

Hello,

I am trying to update product prices and I am unable to do so.  I am using Open Cart 1.5.4 and looking at some YouTube videos I realized that when I go to Admin and go Systems and then Settings I notice I don't have Live Update to proceed. I am on a server.  I am also having problems incorporating Fed Ex. I hope you can help me.

Thanks a lot
