i downloaded metasploit 3.1 and the install was flawless.
i downloaded ruby as well same results.
now when i try and open "metasploit gui or metasploit web" it just show quick dos box and disappears. The gui doesnt even open at all. Any ideas what could possibly be wrong?

further more info: im currently running "vista home pre"

No actually im getting the same output even before i downloaded ruby.
i downloaded metasploit the first time without ruby installed and got the same results. everytime i tried to open metasploit web it was just a quick dos box and dissappears and metasploit gui dont even open.

So i tried downloading ruby, and the samething happens.
it shows a quick dos box and disappears.

Have you downloaded netcat and just clicked on the program and it just showed a quick dos box then closed unless you put it in a particular directory?

Thats exactly what metasploit 3.1 is doing to me. just showing the dos box whenever i click on the metasploit web.

ok so ive just downloaded metasploit version (3) and works perfectly.
i cant get 3.1 to work properly so i just backtracked a bit. I'm just going to use version (3) instead of (3.1).
