Also, i can open from unix supercomuter through Xterm server. but i failed to get molecular electrostatic map. and when i read molden website, it says that i have to use desktop version not Xwindows.
There are some windows version of Molden on the official fpt site (path linked below). I think the native version runs of windows 7 (is the updated one) and it is not necessary a Xwindow server running.
