Need a mouse driver

I sure could use some help from some of you more knowledgable computer folks. I moved an older Computer running Windows 95. Now it is telling me that Microsoft Mouse Driver vers. 8.20 is missing, and I cannot get the mouse to work. I made it search for the files, and it came up with nothing. What did it do with it?? I thought I could go onto the Microsoft site and download it, but there is way too much technical stuff there for me to find what I need. Can any one help me?? What I am thinking I can do is find the driver, download it to a disk from my other computer, and load it onto the old one. It is not easy to navigate without a mouse, I never learned the commands without a mouse since Dos, but I think I can do it. Help??
