The Jivaro client doesn't work and the client doesn't start and no error message is shown.
Try to open a file browser and paste the following into the address bar:
Check if there is a file there with a name that starts with 'qtsingleapplication-' and ends with 'lockfile' .
If you find it, delete it and try starting jivaro again.
If this does not work, please contact firstname.lastname@example.org
