It's not even showing up the mouse in device manager. I have installed synaptic drivers from dell website. External usb mouse is working flawlessly. I am using windows 10 professional 32bit.

Are you sure 3545 is a Model? Doesn't come up through any search.
Looks like their website doesn't list it either. Check their website to see for the exact model and if it's a windows 10 supported driver.

Windows 10 32 bit driver are not available on dell website. WIndows 10 64 bit is available. I've use windows 7 32 bit driver( as win 7 was only available for 32bit drivers). The main problem is why the mouse is not listed in device manager. If it was listed, I could have managed to work it.

If you read the Driver name for the Touch pad under the Windows 10 64-bit section, it looks like a 32bit driver:

Dell Touchpad Driver View details
Input_Driver_CN4KX_WN32_19.0.9.4_A00.EXE | Update Package for Microsoft® Windows® (62 MB)
Mouse, Keyboard & Input Devices|Release date 30 Jul 2015|Last Updated 31 Jul 2015|Recommended
Version 19.0.9.4,A00

Attention on the name "INPUT_DRIVER_CN4KX_WN32". Have you given it a shot? I understand you've tried the Windows 7 already. Won't hurt giving this one a shot.

Also important to note that the link you provided says the Model is 3542. I'm not a Dell Expert, but make sure they match as well

Verify that the Service Tag provided this model.

@andygoesvroom the driver you suggested was for 64 bit only. I've already tried it, it never installs
