RE: Dell Touchpad gestures not working on Dell Inspiron 5558

I found the fix here. Install Synaptics 19.15.2 Windows 10 64 Bit  even tough you have Windows 8.1.

Install like this:

1) Extract the files to another folder

2) Open the folder with extracted files copy the path of the x64 drivers

3) Go to Control Panel>Device Manager>Mice and other pointing devices

4) Right click mice and other pointing devices, select Update Driver>From Hard-Disk

5) Add the x64 drivers path

6) Select Dell Touchpad

7)  Install drivers

8) Restart
