Thank you very much,I have done!

I have the

Dell Inspiron i3531-1200BK 15.6-Inch Laptop

with win8.1.  The DellTpad application crashes everytime I run it.  Even in compatibility mode for win8 and win7.

I still have no one finger scroll aka edge scroll aka linear scroll

one finger scrolling

edge scrolling

linear scrolling

i3531

It is so close but it is buggy then crashes.  The scrolling page has only words on it.  All the other tabs look fine.  I can't set anything.

I do appreciate the help.  I'm currently working with Dell customer service on this issue but so far no luck.  They told me to try Synaptics default driver but it will not install.

DMR_2011 did you ever find  a solution to this? I'm having the same issue! :( 

This TOTALLY works for Windows 10 on a E6420.  thank you so much for this tip - kept fighting this one for hours and finding DellTpad.exe was absolutely brilliant - thanks so much.  I much prefer one finger scrolling along the edges versus that two-finger scroll/pan.  it just doesn't work very well at all

Great I found this old postings..that DelltPad.exe worked great...I spent so much time trying to single scroll. I almost uninstalled win10.

This drive versions of DellTPad.exe works, when replaced in C:\Program Files\Synaptics\SynTP for my Dell Inspiron 15 3542, while the original DellTPad.exe crashes on opening. Thanks a lot!

I initially missed this feature (though not enough to find a workaround), but having used two-finger scrolling for a while now, I have to say I've found it far superior. First, it seems to be identified as a scrolling gesture far more reliably than edge scrolling ever was, but even more importantly, it's more convenient and MUCH more efficient. I typically navigate the touchpad with my middle finger, so my index and/or ring fingers are already hovering over the touchpad area anyway, and I've found it's far faster to simply put 2 fingers down wherever they already are than to move to the extreme edge of the touchpad (displacing my entire hand in the process) just to scroll momentarily, only to have to move my hand back over the touchpad or keyboard to accomplish my next task. I'm very sensitive to hand motion inefficiencies like this because I type 140 WPM on a good keyboard and I use keyboard shortcuts as much as possible to minimize using a mouse/touchpad at all, since quickly pressing a key combination while your hands are already in the keyboard area is almost always much faster than moving your hand to another peripheral and THEN moving the cursor to a specific area of the interface just to execute the desired action, which may then be buried under a few pop-up menus. I actually use PgUp/Dn and the arrow keys for a lot of my scrolling for this exact reason.

Obviously everyone is different, and if you tried two-finger scrolling and hated it, then fair enough -- but if you just miss edge scrolling and never really tried to get used to the replacement gesture, I would encourage you to give it a fair shake before writing it off.

I do NOT however like the new default scroll DIRECTION.  When I'm using a touchSCREEN, I can see moving my fingers up in order to scroll down, since that has the illusion of directly touching and moving the content.  But with a touchPAD, I want a downward motion to scroll down, since in that context the idea is that the content is static and you're moving a "portal/window" down in order to see what's below.
