I am used to have left button of touchpad configured as middle mouse button. I got a new Acer notebook with Windows 10 (had 7 previously) and didn't find how to make this setting. I contacted locar Acer support via mail but despite providing serial number I got answer like "it depends on installed hardware and software". Acer technical help doesn't know hardware and software configuration of their current notebooks??? I asked them to provide some more relevant information but didn't get any answer for more than a week. So I asked at Microsoft if they know how to fix it. Someone there tried hard to help (what a shame for Acer - evil Microsoft having much better support) but to no avail. He said Synaptics touchpad is needed for such settings. According to Acer website it should be preinstalled on the notebook. But it wasn't. We installed all touchpad drivers we have found on official website - but Synaptics settings didn't show up. He didn't know what we could do more. I wanted to ask on chat on Acer website but after filling my computer's serial number in Live Chat page I got: "Our records indicate the serial number you have entered is no longer eligible for warranty support." The notebook is one month old! No support then??? I hope I will get some help here since I don't know where else to ask and I am becoming desperate.
