I am using this this topic because I have the same issue with the installation.
I am using the 64 bit live iso with gnome.
The latest version of the installer appears to be 0.14.113 - a message for checking for updates appears and that’s it. Started Cnchi with the terminal command: sudo -E cnchi -dv and pasted the output here.
Finally the error code is 211229.
Hyllus, my VLC was not able to open when I tried the right click on a movie file -> option “open with -> VLC”. Then I tried to open the player by itself first and then it started every time with no problems. I think the reason could be in the first dialog screen on which VLC asks the user something to confirm (I forgot what was it).
So make sure that you open your player from its icon first. I hope that can help you. Regards.
