Hello,
I just bought a refurbished VN7-791G direct from Acer. It only has a generic mouse driver installed for the trackpad, called "HID-compliant mouse". The multi-touch gestures don't work with this driver and the trackpad is ridiculously sensitive, so I need to install the real driver. I looked here on acer.com and it shows the Synaptic driver for this model (VN7-791G). When I tried to install it, first it gave a generic error and wouldn't process. So I googled and read that Synaptic doesn't sign their drivers correctly so you have to restart Windows allowing unsigned drivers in order to install it. So I did that, then it said "Not needed (No device for update present)" and wouldn't install. So then I downloaded the drivers directly from the Synaptic website, which were oddly an earlier version. Those I finally got to install, but once it did, the track pad stopped working completely and Device Manager said "insufficient system resources exist to complete the api". So I uninstalled that and am back to the generic one.
I really don't want to return this because I've already gotten rid of my other one and I work from home, so I can't be without a computer. But this trackpad is basically unusable as-is. Just in typing this message it has moved my cursor to random places at least 5 times, even though my hands are a full inch above the trackpad. It is just way too sensitive.
I just need to know what drivers to download. The trackpad's hardware ID in Device Manager is "HID\VID_06CB&PID_2970&REV_0008&Col01". Please help.
