Question [Q] Google now launcher for LG G2

Guys I'm looking for a Google now launcher for LG G2 which works with Google search version 3.5. The apk installs but on launching the app says Google search needs to be updated. Anyone know where I can get the apk which works with Google search 3.5?

The ok google function stopped working on the earlier version I had installed and I tried to Uninstall and reinstall but the apks I have found so far don't seem to work with Google search 3.5.

Alternately can anyone suggest what I need to do to get the ok google everywhere functionality to work with stock LG launcher? Currently it doesn't work even after launching google now. I have language set to US English and the keyword detection is turned on.
