To the X server? You might need to play around with xauth / xhost to disable security and try it again (the secure, correct way is to use XForwarding to local host from Windows PuTTY under Wine, or setting the xauth stuff up properly) (Since I would guess that an XClient under Wine is not informed of the X environment that Wine is running under) If it requires X, it seem likely that it is a Windows port of a Unix program. Isn't there a Linux version? (Or you can run it remotely and forward the X to your Linux PC if needed (XForwarding over SSH / DISPLAY with xauth set up))
