I'm stuck and I'm hoping someone can help me here. This afternoon I was given a Dell desktop with Vista to fix. This person claims they uninstalled IE and instead installed FireFox. I thought ok simple fix I'll go into the computer uninstall FireFox and re-install Internet Explorer. I went to do that and successfully uninstalled FireFox. I then started to install IE 9 from my thumb drive but I get an error say "Internet Explorer did not finish installing Setup can not continue because a more recent version of IE is already installed on your computer." I then went to Add/remove programs to delete IE because I figured something got messed up but IE is not listed in programs. It is however still listed on the start menu and when I click it it doesn't launch it just instantly pops up saying IE has stopped working. I really don't know what to do. It's as if it is there but not there.
