I have acer E5-522G, my touchpad suddenly stopped working , so I tried of re-installing the drivers from the official acer website. When installing, it said to uninstall the previous Synaptics drivers. I did the uninstalling and then tried to installed the newly downloaded drivers from Acer.com . It said installation failed. Then I tried installing Synaptics drivers by searching on the internet, 2-3 synaptics drivers installed and everyone gave the message "Ready To Use" with a tick mark. But still the synaptics drivers aren't listed in Programs and Features nor the TouchPad is working without them. Please help me out. I'm on Win10 x64 bit and I've been using it since 8 months
