My 4 mth old laptop touchpad clicks have suddenly stopped working. I've tried re-installing the relevant software although when opening I get a 'software not found' message. I've reset the Elan options to default too. The touchpad works fine for mouse scrolling but neither the left or right click pads nor the main pad clicks are working.
I'm out of ideas now and am hoping it's not a hardware related thing. tbh the touchpad has never been brilliant. It would open a right click menu by itself although that stopped a while back. I'm going to try a system restore next. I'm just thankful I managed to find an old usb mouse
Just wondering if there is anything else I should try before ringing Lenovo technical support.
Thanking you all in advance

A few questions
What version of Windows are you running?
Are you getting the "Software Not Found" error when trying to install the Touch Pad driver, and if so, have you tried saving the installation file somewhere other than in the downloads folder (e,g, on the desktop)?
Have you tried first uninstalling the touchpad driver before reinstalling?
Hopefully your system restore will work, but running a standard disk check ( chkdsk c: /f ) might be in order too.

Typically the "software not found" message would indicate that a prerequisite software application is missing in order to install a patch or update, so I am at a loss as to why you are seeing that error when running the installer.
Are there any details given in the "software not found message" that might point to what "software" the installer is looking for?
Have you scanned for malware using something like Malwarebytes free scanner (note that at the end of the installation, you can choose to opt out of trying the full version that runs in realtime, and just use the free manual scanner)
Have you tried installing the driver in Safe Mode?

I understood what you were saying, but it seems that the installer for the touchpad driver is looking for some other software/driver, and it may be the lack of the other software/driver that is causing your issue.
It is possible that the ribbon cable that connects the touchpad to the motherboard is a loose or damaged, which is certainly possible, but the error during the driver install is mighty suspicious too. If your system is under warranty, then you might call support and open a ticket. If not, and you feel up to it, you might be able to remove the back cover and see if there is a loose connection. You can find the Hardware Maintenance Manual for your system at the http://support.lenovo.com website for your paticular model were you download drivers from the "Documentation" link within the blue band.
One thing you might try is to run Windows's System File Check utility to see if perhaps a Windows system file is corrupt or missing. It can take up to an hour to run, and may appear to freeze at times, but just let it run until it complete. It will attempt to replace any damaged or missing Windows system files from a backups stored in the Windows Component Store. If it cannot repair one or more files, then you will have to run DISM to first to fix the files in the Windows Component Store, and then run the SFC scan again to fix the files previously unrepairable.
How to run an SFC scan
Let the scan run till complete, even it if does appear to pause, which it will do from time to time while working.
You should get one of three results.
How to run DISM (Windows 8.x and 10)
Note: An Internet Connection is required to run DISM
Once DISM completes, you must run another SFC scan to repair files that the SFC scan was previously unable to repair.
