In previous versions of opensuse, I clicked on them and the yast-install prompt would show it. How do install these RPM files? Superuser mode. Similar to installing the multimedia package.
there are 2 rpm’s there
you can download them right-click on them and chose install software
or use zypper and install them directly (they will be downloaded in a temp folder)
assuming you want LightScribe Labeler not the Host app just paste this in a terminal
sudo zypper in http://www.lacie.com/files/lacie-content/download/drivers/LaCie%20LightScribe%20Labeler%201.0%20Linux.rpm
Problem: nothing provides libstdc++.so.5 needed by lightscribe-1.8.15.1-0.i386
Solution 1: do not install lightscribe-1.8.15.1-0.i386
Solution 2: break lightscribe-1.8.15.1-0.i386 by ignoring some of its dependencies
Extract the rpm and dump the lib in /usr/local/lib/ then run ldconfig and see how that goes (you may need to break the install, option 2). The other option is to extract the lightscribe rpm (as your user in you home dir) and the dump the lib in the directory.
