Error while installing SharePoint Products and Technologies Configuration Wizard

Hi Guys,

I am getting following error while installing MOSS 2007. When I am running SharePoint Products and
Technologies Configuration Wizard, after passing database server, database name and access acount information (username, password) when I click next, it says

An error has occurred while validating the configuration settings. An exception of type System.MissingMethodException was thrown. Additional exception information: Method not found: 'System.String Microsoft.SharePoint.Administration.SPSqlConnectionString.GetWYukonSafeConnectionString(System.String)'.

Is it because I am passing wrong username and password? I think I am entering correct database instance and its access permissions. Please help guys. I really appreciate your time.

Did you install the required software properly (like service packs etc.)?
