To install a .cab file you go to device manager & right click on the device you wish to update, choose update driver then manually search for the driver & choose the folder containing the downloaded update/.cab file & choose next, this should then install.
Synaptics software accidentally deleted
Following some problems with a 3 year old Acer Cloudbook I had a PC shop re install a fresh Windows 10 and delete the original version. I had previously done something to change the touchpad settings and had resolved it by installing updated drivers. I think I might have moved the drivers to a flash drive and then deleted them by accident.
The new install doesn't allow the touchpad to work properly. I have no touchpad according to device manager merely a mouse. However, I am physically using the touchpad to navigate but it will not scroll or pinch to zoom etc. It will move the pointer and nothing else. The touchpad is therefore in existence somewhere on the laptop but the device manager doesn't have any details of it. Settings does but only allows me to change the delay time. Nothing else. It seems I have completely deleted the software.
I have tried updating the drivers for touchpad via Acer website but when competed the drives download but I get a windows error message saying this device doesn't work on my laptop. Any ides of how I can recover the driver software would be greatly appreciated.

2019-09-26T22:09:58+00:00 I have tried a few times but for some reason device manager won't recognise the downloaded file for driver in my downloads file.. It is there but device manager won't allow me to find it....It is something called a cabinet file apparently. Might not be the correct file but at least I have HID compliant device and HID compliant mouse in device manager now. One of them is surely the touchpad…..I will try again tomorrow. I have a feeling we might be near to some success now....Whatever files mat have been corrupted are surely fixed now

If the original scan doesn’t find any problems then this is not needed.
