Alps Pointing Device driver not working in Windows Vista

I installed upgraded in Windows Vista. After the upgrade I found that the touchpad is not working. I am able to use a mouse on the same. It shows Alps Pointing Device driver is missing. I tried to found the driver on the official website. But not able to locate proper drivers. I hope Vista has drivers available for my laptop. How can I locate the same. .

The only way to locate proper drivers is to find from the official manufacturers website. You can provide the laptop model here then I can help you to find the same. The official site if does not offer you right drivers download then there is no way you can use Windows Vista on it.
