I have downloaded and extracted http://download.knime.org/analytics-platform/linux/knime-full_2.12.1.linux.gtk.x86_64.tar.gz (and also tried http://download.knime.org/analytics-platform/linux/knime_2.12.1.linux.gtk.x86.tar.gz).
Trying to launch knime always gives popup with:
"The Knime executable launcher was unable to locate its
companion shared library."
From command line :
"plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.100.v20110505: cannot open shared object file: No such file or directory"
(plus the popup)
I have an uptodate Ubuntu 14.04.3 LTS 64-bit
