Internet explorer 7 is able to be installed only on windows which were installed with an original product key. So when you install the program it search if you have an original product key installed with Microsoft genuine validation. If not the setup will cancel. To find out if your computer is genuine go to this site
http://www.microsoft.com/genuine/dow...3f136&Error=20. If you are genuine you do not need the following instructions. If not, I have found a way to install internet explorer 7 without having an original product key. Just read carefully the following instructions below and do what it says in order to change the product key and replace it with one that is genuine.
1. Go to Start and then press run.
