Are you installing the fresh package of drupal? This may happen if you are using the same drupal package which you have used earlier

I use this file: "drupal-7.22.tar.gz"
I was installed this more than 1000 times but this error is a new issue!

Let's check again:
I had a Drupal in localhost
Then i removed Drupal folder and database
Then i extract drupal-7.22.tar.gz in www folder
Then create a database
Then give that error
Then i change folder name and db name
Then i clear the browser cache
Then i restart apache service
Then i reboot Ubuntu (my OS)
After any level that problem was stay! :|
:(

drop, not just empty, the whole Database tables.

Also be sure that the settings.php is a copy of the default

After all the problem was stay!
but i installed Drupal in another way: Replacing 127.0.0.1 by 127.0.0.2 and installtion was successful :)
thank's :)

Sounds like a weird cache problem

I'm having a similar problem. So Thanks!
