Need help installing z97 motherboard drivers

[shmnz]

Hi, i am a little confused installing audio drivers on my ga z97-d3h mobo. Installing drivers from motherboard driver CD was easy for me but when i visited gigabyte website i found a update to my Realtek HD audio driver was available  i downloaded the update and opened the "Realtek" folder and saw two setup files there i really don't know which one is the right one. Pls see the attachment below and clear this for me . Thanks

I have Z97X gaming 5 and I launch "setup",  My realtek driver is the same
probably "isetup will install" automatic

Or simply launch the run.exe at the root of the CD and install the audio driver via Gigabyte's graphical user interface.  It's not that evil.
