It seems to be missing settings and have no option for one-finger scroll after driver update for ELAN Smart-Pad version 11.15.0.14.
I found a working solution, and it even uses an updated driver!
- Open Internet Explorer (Sorry, doesn’t work on Edge or any other browser)
- Go to Microsoft’s update catalog
- If the screen you get is solid blue or missing the search bar, you might be missing a plugin. Refresh the page and there should be an option to install it.
- The page should now look like this. Search “Elan Input Device”.
- Press the “Last Update” column header. It should now be sorted by the most recent release.
- Click the titles on both of these (you may need to enable popups). Check inside the popup if the architecture is for AMD64 (64-bit) or x86 (32-bit). The reason I ignored the top two results is because they are exclusively for Toshiba pcs.
- Click “Add” ONLY if the driver is both compatible with your OS version (Windows 10) AND the correct architecture for your system (AMD64 = 64-bit Windows ; x86 = 32-bit Windows). If not, close the popup and keep selecting titles until you find a match.
- Near the top right of your screen, you should see “view basket (1)”. If you have a number, sucess, your driver has been added. Click on it.
- Press “Download” and curse Microsoft for their convoluted driver update system.
- Choose where you want the driver to download (I just chose the default Downloads folder).
- Locate the downloaded driver file (.cab). Extract it to another folder by using WinRAR, 7zip, or open a command prompt and use expand[2] .
WHAT? WAIT. HOW DO I INSTALL IT?
Manually.
- Open “Device Manager” (Right Click on Start Menu).
- Locate “Mice and other pointing devices” and expand it.
- Right click on “ELAN Input Device” and select “Update Driver”.
- Choose “Browse my computer for driver software.”
- Choose “Browse” and select the folder where you extracted the driver files.
- Choose next and cross your fingers. Restart your pc after installation for the changes to apply.
- Head back to device manager, right click “ELAN Input Device,” and select “properties.” It should now be version “15.6.2.1.”
- Navigate to: Settings > Devices > Mouse & Touchpad > Additional Mouse Options. See if there is an ELAN tab.
- Enable it if necessary. Then choose options.
- This window should appear. Choose “Edge Scroll”, enable Vertical and Horizontal scroll, and apply your changes.
- You should be all set, this solution worked for me and I hope it works for you too! (P.S.: I basically expanded upon this post and changed the instructions from the sound driver to the Elan driver, as well as going into more detail on some instructions.)
