I have a similar problem.
I enter all the info of the database and click on next. respond yes to "You will be asked if you are sure that all these data are correct. If you are, press Yes".
I press yes and get a index2.php blank
try with firefox 220.127.116.11 and ie 6.0.2900
I has this situation too. I use firefox 18.104.22.168 and ie 6.0.2800. Solved easy, just daleted all instllation files from installation folder and copy new one. Clear MSQL database for this site and repeate installation process.
5 or 7 times i'm not sure. But now all work fine.
