Hello all!

I'm trying to change the default browser from Fire Launcher to Google Now Launcher. I'm on the Kindle Fire 7 5th gen, running 5.1.4, not rooted. I'm sure the answer is that I need to root to change the launcher, but I thought I read a post somewhere that said you could.
When I try to select Google Now, I get the attached notification. However, when I go into settings there is no Home option...

Any help would be greatly appreciated! I'm not against rooting, the issue I'm having is getting ADB and the proper drivers set up on Windows 8.1

Thank you,
