After first install (Windows XP 32-bit or Windows Server 2003), redmine throws '500' error. From the log file:
ActiveRecord::StatementInvalid (Mysql2::Error: Table 'bitnami_redmine.settings' doesn't exist: SHOW FULL FIELDS FROM `settings`)
It seems that installer doesn't create the redmine database. All is well if i don't use special characters in the user name (underscore, in my case).
