I have a Compaq Presario Laptop working on Windows Vista. The touch pad mouse on the computer has stopped working for the past 2 days. I have tried to install the recommended update 'Synaptics-Input-Synaptics PS/2 Port TouchPad' but it has failed the on the past 20 times I have attempted with an error code 80040216 reported as the reason.
I have no other programs running and I have tried a System Restore to a time prior to the problem without success.
Any help would be greatly appreciated
