You don't need to run msi software. it is useless and hogs down the laptop.
The touchpad is made by elantech, one of the three makers of touchpads ( the others are alps and synaptics). elantech is the second best, or should I say the first worst. Synaptics makes the only good touchpad, and the elantech one is mediocre ( alps is even worst).
Elantech was supposed to provide driver updates for their touchpad line ( they have two products: the bad one: version 3 touchpad that comes with the msi notebook, and version 5 that is supplied on some packard bell laptops).
their site is at:
http://www.elantech.com.tw/english/en_home.html
I sent them a mail a few weeks ago, because the driver was not online. I recived no response, and I noticed that they removed the driver page.
MSI site has driver version 3.0.2.0 for version 3 touchpad. The latest driver version for this touchpad is 3.0.2.2 and you can find it at targa site:

browse for notebook targa traveller 826 mt-32. you will also find a newer driver for the onboard modem than the one provided by msi.
