Hi,
for install client components with SQL Server 2005 Express Edition i use
this command:
"setup.exe /qb ADDLOCAL=Client_Components"

and with SQL Server 2008 Express Edition i try this command:
"setup.exe /qs /ACTION=Install /FEATURES=BC,Conn,SSMS /HIDECONSOLE"

but client components (for example feature called "SQL Server configuration
manager") are not installed.

Is possibile install all client components (include "SQL Server
configuration manager") without install an instance?

Many thanks for your help
