You need to download the correct version of the software in order to run properly. I have downloaded the application on a 64bit system, but the message was the same, then I have downloaded 32bit version and encountered the following error:
[29408:0511/064353:ERROR:zygote_host_impl_linux.cc(146)] Running without the SUID sandbox! See https://code.google.com/p/chromium/wiki/LinuxSUIDSandboxDevelopment for more information on developing with the sandbox on.
(muvconf:29408): Gtk-WARNING **: cannot open display:
I don't have a display, only a terminal, but the application should start with X started. Download the 32bit version instead.
