I'm back!
I uninstalled the driver update app and rolled back the touchpad driver to a previous version. Once I re-start, the current version gets reinstalled again. So I think I am back to square 1.
I haven't been successful in installing the precision touchpad driver after that.

The HP Support Assistant software analyses your system and can find and install the correct update for your device (later).

For now a small Registry hack may also help with disabling (if not correcting the other driver/software problem) if the other solution doesn't help yet and you feel secure in using the Registry directly.
First open Registry editor (type RegEdit.exe in Search) and go to HKEY_CURRENT_USER\Software\Synaptics, HKEY_LOCAL_MACHINE\Software\Synaptics and HKEY_LOCAL_MACHINE\Software\InstalledOptions\Synaptics, Right-click 'Synaptics' and choose Export to create a backup file with the current settings (3x).
Put this in a text file:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl]
"ShowResetButton"=dword:00000001
"RestoreAllDefaults"=dword:00000000
[HKEY_LOCAL_MACHINE\Software\Synaptics\SynTPEnh]
"DisableIntPDFeature"=dword:00000022
"TrayIcon"=dword:00000011
[HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTP\Configurable]
"DisableTouchPadIfMousePresent"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTP\Defaults]
"DisableTouchPadIfMousePresent"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTP\Install]
"DeleteUserSettingsOnUpgrade"=dword:00000000
[HKEY_CURRENT_USER\Software\Synaptics\SynTP]
"DisableTouchPadIfMousePresent"=dword:00000001
[HKEY_CURRENT_USER\Software\Synaptics\SynTPEnh]
"DisableIntPDFeature"=dword:00000022
"TrayIcon"=dword:00000011
Rename the text file to TouchPadHack.reg, Right-click and choose Merge. Restart your Laptop (or Sign out maybe) to see if this works for you now.
(Maybe more details later.)
