I fixed above problem by changing php.ini file, set register_globals = On

now I still got the blank page during install.
but running the php by command line gave this:

C:\Inetpub\forum>c:\php\php-cgi index.php
X-Powered-By: PHP/5.2.13
Set-Cookie: PHPSESSID=77cgi7iekl71u53eld2dj7af22; path=/

Anyone can help?
