Touchpad driver issue: Windows 7 on E5-774

I purchased an E5-774-33DT and I decided to "downgrade" from Windows 10 Home to (genuine) Windows 7 Professional to stay compatible with my work laptop and my main desktop.

 

I am using "Legacy" in stead of "UEFI" boot option to start Windows 7.

 

Everything seems to work properly now, except for my touchpad. It is a "clickpad" version without any seperate buttons.

 

I tried several drivers from Elan / Synaptics / Alps without any luck.

 

It works as PS/2 device, but I would like to use multi gesture (especially 2 finger scrolling and zooming), disable the touchpad while typing, disable the touchtaps, etc. I tried "Basic" as well as "Advanced" setting in bios/uefi.

 

Is there anyone who could point me in the right direction?

    Yesterday I did a bunch of trial-and-error and I got lucky when I installed "touchpad_ELANTECH_11.6.24.209_W7x64_A" driver which is supplied for Acer E5-571 notebook.

     

    It turned out that some other Windows 7 64bit drivers for E5-571 (especially "Audio_Realtek_6.0.1.7300_W7x64_A") were very helpful for my E5-774 as well.

    @Eliteman, thank you for taking your time to help me. This time I got lucky by trial-and-error but I am sure your tool suggestions will be handy for future driver issues.

    Maybe buying a mouse would be better because it more accurate and easier to use, all you need to do is plug it in and you're ready to go. Also it's very easy to carry around. But if you don't want to buy a mouse I could do some researching for you.

    Hi EliteMan, thank you for your workaround suggestion. Yes I am using a mouse and that works fine. There are 2 issues with this workaround: when I use the keyboard the touchpad is still active and that is pretty annoying. Also there are situations where I prefer to use the touchpad.

     

    Please note that my touchpad operates fine as standard PS/2 device so I can move the pointer en left/right click with it. But as mentioned I can not use the additional functions as described in my opening post.

     

    Any help in getting this to work is appreciated.

     

    Is there a way to determine the brand/type of the touchpad? It now automatically registers as PS/2 device in WIndows 7.

    Okay so I might have found what you are looking for. Apparently it only works with Synaptic mousepads.

    Speccy will tell you all about your hard ware. Go to peripherals and it should tell you what you mouse pad manufacture it is.
