No problem, but before you go. A lot of people have had the same problem and have solved it by disabling their anti-virus/spyware and then re-booting their PC in 'safe mode with networking' by pressing F8 during boot time which allows you to connect to the internet, and then run the IE7 installation again.

When the installation is complete reboot the PC, turn your anti-virus/spyware back on and run a scan.

Good Luck!
