Problem Installing second wordpress local

Hello

i installed xamp and then wordpress through bitnami , so everything was very easy because it created a data base automaticcally and also config file.
Now i am trying to install the second wordpress instalation on htdocs , i created another databae called prueba_wp and i configured the configsample file but then i write
local/wordpress2 and it comes the message to write the database and password.
I dont understand why because i have already written that on the config file but i write it again and then i come with this message

“This either means that the username and password information in your wp-config.php file is incorrect or we can’t contact the database server at localhost. This could mean your host’s database server is down.

Are you sure you have the correct username and password?
Are you sure that you have typed the correct hostname?
Are you sure that the database server is running?
If you’re unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums.”

Any help please

Thank you
