Database not installed

Hi all, could you help me to solve my problem?

During an installation, just after clicking on “Run the install”, this error message appears:

WordPress database error Table 'paveldolezal.wp_options' doesn't exist for query INSERT INTO wp_options (option_name, option_value, autoload) VALUES ('cron', 'a:2:{i:1225566131;a:1:{s:17:\"wp_update_plugins\";a:1:{s:32:\"40cd750bba9870f18aada2478b24840a\";a:3:{s:8:\"schedule\";s:10:\"twicedaily\";s:4:\"args\";a:0:{}s:8:\"interval\";i:43200;}}}s:7:\"version\";i:2;}', 'yes') made by add_option WordPress database error Table 'paveldolezal.wp_options' doesn't exist for query INSERT INTO wp_options (option_name, option_value, autoload) VALUES ('random_seed', 'db595a2a02d75a7c124a489827088188', 'yes') made by add_option WordPress database error Table 'paveldolezal.wp_options' doesn't exist for query INSERT INTO wp_options (option_name, option_value, autoload) VALUES ('auth_salt', 'HURW3dGwSSZM', 'yes') made by add_option

Of course, no table is installed in database.

I use root user in MySQL 5, localhost, IIS 6 server with FastCGI. And I’m sure that I typed all database information correctly.

Thank you for advice, ideas…
