Thanks in advance for any help! My logitech corded laser mouse has bad contact points, so I got a corded Microsoft Intellimouse to replace it. The problem is that when I try to install the drivers, it fully removes the logitech mouse, leaving me without a mouse at all. If I don't let it remove the logitech mouse, it won't install the drivers-catch 22. After that, it would not let me reinstall any mouse at all and I had to use system restore. The very first screen on the microsoft drivers is the agreement and I cannot mark that I agree if I don't have a mouse. If I could find a way to mark that, I'm sure I could use arrows, tabs and enter to complete setup, but tab just defaults to cancel setup and enter does not work because it won't fully highlight. The intellimouse isn't found by the computer after turning off and plugging it in either-tried that. I thought that, since my operating system (XP) is made by microsoft, the drivers might already be in there. No such luck. The instructions say the drivers must be installed first and I would like to do that, but I am stopped every time. I have tried reinstalling my dinosaur roller ball mouse that came with my system and it won't do that either.
