Go to Settings->Bluetooth &Devices-> Touchpad, expand Scroll &Zoom, tick the box for Drag two fingers to scroll.
it is not showing scroll and zoom
Go to BIOS screen and move to Main tab, check whether the Touchpad is in I2C mode or not, if it isn't switch to I2C mode as shown in the picture.
it is also not showing touchpad option
While you are in the Main tab, press Ctrl+S buttons together and see whether the Touchpad option appears.
no its not working
You could try reinstalling Serial IO driver, go to Acer Driver support site and download version 30.100.2042.1, then uninstall Serial IO driver in Device Manager and without restarting install the driver downloaded.

If it is still not working ..
Try fn + f6 or f6 alone or fn + f7 or f7 alone on keyboard to disable and enable the touchpad.
Please look at the key f6 and f7 key on keyboard . You can see the hand symbol with fingers . That denotes the touchpad function key. On some models it will be on f6 and some models it will be on f7. So we need to use the right key depending upon the laptop model . If fn + f7 is not working then we have to use f7 alone to make it to work.
On some old laptop models there will be a separate button right next to touch pad area which is below the space bar. It is used to turn on and off the touch pad. On some old models it will be right next to power button. On all new models, f7 key is used to enable and disable the touch pad.
If you would like to disable and enable the touchpad, please press and hold fn key on the keyboard and then press f6 or f7 once. If the touchpad is not getting disabled you can either press f6 alone or f7 alone without holding the fn key. It is used to enable or disable the touchpad..
After disabling and enabling the touchpad check how it is working..
