if you don't know how to install, you could bring your phone to Nokia shop. Noka salesmen/salesgirls are very nice and kind. They are willing to help you but you need to wait for about 15minutes for installing.
If you did not have a time, you could follow processing to install
1) unzip the file .rar to a normal file name and mark down the filename and location.
2) install "Nokia PC suit"e software to your computer
3) open pc suite software and press "install applications" icon.
4) see "Nokia application installer" sheet pop-up
5) find the correct location & file name (see number 1) on the left side of sheet, i.e. my computer section.
6) press the "arrow" (direction : from left to right) to intall the software to the phone.
7) from now, you only follow the instruction and press enter for confirm.
hope you could success.
