Installing on iis 7

Hi I am trying to install using mysql and iis7.
I get this error:

WordPress database error Table ‘wp.wp_options’ doesn’t exist for query INSERT INTO wp_options (option_name, option_value, autoload) VALUES (‘cron’, ‘a:2:{i:1227601173;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 ‘wp.wp_options’ doesn’t exist for query INSERT INTO wp_options (option_name, option_value, autoload) VALUES (‘random_seed’, ‘3369e1a9306710b7bba45d390cb3aaae’, ‘yes’) made by add_option
WordPress database error Table ‘wp.wp_options’ doesn’t exist for query INSERT INTO wp_options (option_name, option_value, autoload) VALUES (‘auth_salt’, ‘avUSx)CA)1^H’, ‘yes’) made by add_option

An empty database has been previously craeted in Mysql.

Maybe some php wrong config to connect to mysql??

Thanks
