I have just downloaded and tried to install Internet Explorer 8. It gets to "Installing Windows Internet Explorer Core Components...", hangs there at 100% CPU usage for something like 10 minutes, and then says the setup did not complete. When I restart the computer and try again like it says to do, the same thing happens.
What's going on? Do I have to manually uninstall IE 7 first? I have tried disabling and uninstalling my antivirus program, which doesn't help.
