install sql 2005 vista only client tools install

I can't get the database to install. When I run the set up the check boxes for
Sql server database services created a sql server failover cluster
Analysis services create an analysis server failover cluster
reporting services notification services integration services
are all grayed out.
What I did was run the setup for enterprise edition then sp1 and then tried to reinstall from the original enterprise edition disc.
iis is enabled. as far as i can tell - the management studio does run but i cannot connect the local database (which makes sense because as far as i can tell there is no database to connect to)
what am i doing wrong?
