While installing magento the first window is License Agreement which says
Welcome to Magento's Installation Wizard!"
After accepting term and clicking continue
window appears. Clicking continue button brings the window
In the configuration window you will see Database Connection, Web access options and Session storage options. After filling forms you may face problem that clicking continue button will not proceed further and also it does not display any error messages.
Cause of the Problem
The installation does not proceed because either host, database name, user name or password field value is wrong. If you pass any wrong information to those fields then installation will not proceed.
Solution of the Problem
Before proceed installation be sure that host, database name, user name and password field are correct. You can test those from your command line. In mysql database using mysql command line interface try to login using the information that you provided in the magento configuration. If you are successful then be sure that your database name is correct and you can connect that database using your user name and password.
Also make sure before installation database you must create a database. On your mysql prompt you can do it by simply,
mysql> create database magento;
Query OK, 1 row affected (0.06 sec)
If you want a dedicated user for magento then be sure to create that user too and give permission to that user to access the database.
After you put all right information click continue button and you will see installation proceed.
