I have been trying to install IE 6.0 which will not install. I have downloaded the full version and it still won't install. I can't install it either as it doesn't show on the add/remove programs list.

think have you recently installed a program ?? If so uninstall it and re
install again some components could have been left out. If not , next step
is to call a dell tech I wouldnt be surprised if you have to format.
