Does the installer itself download without a problem?

Does the installation stop at a particular page (& give you the error) or do you see the error when you first double click on the installer?

Which OS are you using? If Vista, do you have an administrator account? If you have Vista but not an admin account, try right clicking on the installer > run as administrator.
