Both controller share many of the same features, the atlas has IOC (intelligent orientation control or headless mode, RTL (return to launch mode), altitude hold mode, stabilize mode.
Installation of this flight controller took less than 15 minutes, the only soldering i had to do was to connect a XT60 connector for a lipo battery, the rest was very simple. The GPS and the LED fit into two connectors clearly marked, the one side of the board has 8 motor connectors and a Power input VIN that comes from the LED. The opposite side has connectors for your reciever. There are three extra channels, the first channel controls the stabilize, altitude and GPS mode. The second controls the RTL, IOC and Off. the third channel is not currently used.
After reading the forums, you can also just tick the Run as administrator box save and run.
Windows 10 blocks unistalled programs from accessing the com port. Seeing as this is downloaded, it has to be run as an administrator.
