Installing Klik in remaster

[s-r-b]

I have booted Knoppix 4.02 CD and I am remastering in a chroot shell. When I try to add Klik...

wget klik.atekon.de/client/install -O -|sh

... I get an error, because the installation tries to open a popup window, that the chrooted environment doesn't allow.

Can someone help me with how to fix this? Will Klik work in the remastered ISO anyway, if I ignore this error?

Thanks for any help!
