Failed to set payload windows/adduser in metasploit,need help

[BlueCharles]

I use exploit:ms08_067_netapi,but when i type:set payload windows/adduser,it shows the value specified for payload is not valid.

So i type:show payloads,and i can't find the payload:windows/adduser,but when i try to search this payload at first,it shows metasploit has this payload.

Why i can't set this payload?I have read other's article and i know this payload can be used with that exploit.

Your command is incorrect if it is the way you are showing us
"set payload windows/adduser"

It should be :

use payload/windows/adduser

You don't set payloads, you use them. Try and let me know.

Sorry, but your wrong. You set payloads. If you try to "use" them it looks for modules to load. WHat he was doing should work as its the correct way.
