If I undertood well, you are trying to install a cluster node in a W7-64
You need to install a non cluster, default instance, in a W7 machine. Because the Enterprise license is really expensive, and intended for server environments, maybe you just want to install a developer or standard license in the W7 machine. See here for the different versions features and verify wich of them do you really need.

Hope this helps

thank you for your reply but i think there is a special configration in win7 future for it
but for your bost i need to work with enterprise i have the license so i need to use
thank's
