What type is shellcode?

Thanks for your answer.

I'm generated via msfpayload.

root@kali:~# msfpayload windows/shell_bind_tcp LPORT=1337 C

Did you resolve this? I too get the same error. I'm not sure if it has something to do with DEP or not. For a workaround try out Debasish's execute shellcode with python method.

No,Im not resolve it,still waiting for answer!
