I just post this matter after I have asking from my friend, how to install "Internet Explorer " on Linux. Sometime, web base application didn't matching the code with others browser. Thats why my friend ask me to do that. I suggest him to use IE4Linux. This is the way I install the IE4Linux on Ubuntu 7.10(Gutsy Gibbon)
1. Make sure you login your Ubuntu Linux with normal user. Don't login as root. Sometime IE4Linux won't come out or launching when you login as root after install.
2. Open your terminal
