I am using XP Media Edition. IE8 kept freezing up when on Facebook. After a few times IE icon disappears from desktop. IE does not appear in start menu. Decided to re-install IE8 and it looks like it installs, but still no icon and still not in start menu. All the time McAfee is running, updated and automatically scans, no reason to suspect virus or other malicious bug. Firefox runs fine. Still IE will not install. I get no errors, it just does not appear.
