Remove Installation Directory

Hi, I have installed Joomla by BlueHost an it works just fine.
Recently I bought HotDestination25 template, read the instalation guide, but when I should start the instalation by acessing
http://www.your_site_address.com/subfolder/index.php I'm receiving this message:
"LEMBRE-SE DE REMOVER
O DIRETÓRIO INSTALLATION COMPLETAMENTE.
Você não poderá passar deste ponto, até que o diretório installation seja removido. Esta é uma medida de segurança do Joomla!."

Already tried to remove joomla from BlueHost and performe the instalation directly, but nothing works. Already tried some different folders. Any sugestions?

regards

Solved by removing all folders and uninstalling joomla from bluehost. than uploaded hot_install directly to /

thanks
