KNIME 2.1.2 x86_64 does not start

Hi,

I freshly downloaded an archive (knime-2.1.2-linux.gtk.x86_64.tar.gz) and extracted it. But when I type the command knime, I got a message saying that the following file is missing:

plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.0.101.R34x_v20080731

What does this mean? Is it something missing from the archive? Do I need to install eclipse?

I am using a Mandriva Linux 2010.0, x86_64.

Thanks in advance for your help,
Gilles MARCOU

Did you check (e.g. with the MD5 sum) that the archive was downloaded completely?
