Hi Guys .. I'm so sry for taking ur vaulable time
I have a problem with installing GNOME on my Centos 64bit . I tried this survey:

1 ) yum –y update
2 ) yum -y groupinstall "X Window System"
3 ) yum -y groupinstall "GNOME Desktop Environment"

the first survey was ok and it has done .
the second survey I got this message : no package to install
the third survey the error was this : Group GNOME Desktop Environment does not exist.

I've just confused up .. what should i do to fix this problem ?

is there any extra command that i should run before them ?

thanks alot

Where did you get the information on installing GNOME? As far as I can recall, and form Googling, you're using the wrong package names -- the first link I found in Google follows and the others I checked seem to agree:
