For this notebook only Win 8 is provided by Acer unfortunately !!
So if you want to let Windows 7 run only once you have a problem with the drivers!
It took 8 hours now and finally found everything and successfully installed
For most components is also the Win 8 driver version.
The driver needed otherwise I linked you down
In this sense, a lot of fun with Win 7 :-)
Windows 7 drivers:
