SQL Server Express 2008

I am tring to install SQL Server Express 2008 on my stand alone laptop. It gets 3/4 way thru and comes back with this message "The Specified credentials for the SQL Service are not valid"   Does anyone know how to fix this?

            Thanks for your help,

Is this a domain PC? if it's a workgroup PC is there a password set for the local account you are using to install the software? And Lastly I guess, does the password you created for the service meet the requirements?

The password must meet the Microsoft SQL Server Strong Password requirements: •Does not contain all or part of the user's account name
•Is more than eight characters in length
•Contains characters from at least three of the following categories: ¿English uppercase characters (A through Z)
¿English lowercase characters (a through z)
¿Base 10 digits (0 through 9)
¿Nonalphabetic characters (for example: !, $, #, %)

This laptop is in my home and is not connected to a network. It also does not have a local password.  Do I need to put a local password on the PC to get this to work?

   Thanks again,

I've seen NOT having a local password setup cause problems. Try that, and or when Server Configuration page opens up and asks you which accounts to use, choose, either browse for you local account and enter the new password, or type SYSTEM for the user, with no password. Give that a shot.
