Try running from a console:
~/.klik xvier
and see what happens.
Exactly what I explain in my first post.
After the installation, I see modifications in fstab, I see new files .klik and .zAppRun in my home, but nothing more happens vhen I choose to download something.....

My distro ( as you can see in my post...) is Ubuntu Dapper 6.06.1 LTS
Thanks, and Happy new Year..!!
