Installing Joomla_1.5.22 using EasyPHP-5.3.3.1 a problem in the database section

I'm trying to install joomla with using easyphp. While I opened localhost website I follow the procedure for the joomla installation procedure. However, when I reach to database section I enter

localhost to "hostname" field

root to "user" field

I left the password field empty.

I enter the database that I want to use

After all these steps have been done, I hit "next" button. However, the ftp website is not opening.

The reason for this problem is "localhost" is not defined in the "hosts" file in the "C:\Windows\System32\drivers\etc" directory. Open this file and add 

127.0.0.1       localhost

Then, try again.
