KNIME 2.1.2 x86_64 does not start


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:


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,

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