I just tried to install TI 9.0 Home Build 3633 on a Windows 98SE machine. The installation appeared to go normally. I rebooted and the TI icon was on the Desktop. However, when I double click the icon, TI doesn't start. When I use Ctrl-Alt-Del to bring up the Task Manager, there is a True Image entry, but when I use End Task, it reports that it is not responding. The True Image Monitor is also listed. This same machine with Windows XP Pro SP2 runs TI 9.0 Home Build 3633 without any problem. I have a mobil hard drive rack, and the operating systems are on two different hard drives on the same computer. Is anyone running Build 3633 successfully on Windows 98SE?
