ok I found a similar post and the recommendation was

This happens if you have already edited the $db_url variable in settings.php. The installer will no longer be automatically invoked, because Drupal assumes installation has already been completed.

To remedy, run the installer manually by visiting http://example.com/install.php.

The recommended solution works

Hello

I am trying to install drupal but I haven't made any progress. I read
through the manuals, I googled for the problem but I haven't found any
solution

Windows 7 64 bit
Apache 2.2.17
PHP 5.3.3
PostgerSQL 8.4 I have even tryed with MySQL 5.X with same behaviour
similar error message.

While trying to install drupal for first time I noticed that nothing
happens.
Apache access.log gave me
"GET /drupal/ HTTP/1.1" 404 -

After googling
I set display_errors = On on the php.ini to see what is happening and
got the following
