RC Cilent on Linux

[comet]

I have downloaded RC Cilent through the login window, and I can't seem to install it.

I already followed the instructions:
" After downloading uncompress ~/graal/graal4/rc/rc.tgz and then run "rc". "

The file in Linux saves as "rc.tgz" and I have managed to extract the file but the it only saves a folder that opens up with all .png images.

I want to know how to install RC and open it instead of viewing a folder full of images. Or, if someone has an alternative download link they want to share with me, doesn't if it's windows because I have windows emulator.
