But any advice is appreciated. I'm new to Linux and still finding it frustrating to use... I'm almost ready to throw up my hands and go back to Windows.
Linux, and Open Source SL clients, sadly tend to both be made by tekkies for tekkies.
If you have a good Linux desktop (but of course I have no idea what distribution you're using), then what you should be able to do is:
1 - Right click on the .bzip2 file on your desktop.
2 - Choose an option which relates to "uncompressing" or "expanding" or "unpacking" it.
3 - Choose to unpack it, and when asked where to put it, choose the directory where you installed Second Life.
If your desktop isn't that friendly, then you'll have to do it manually, which is a pain if you're not used to it. This gets techy, I'm afraid...
1 - Start a Command Prompt (may also be called Terminal, Console, Shell, or bash)
2 - Type "cd ", space, followed by the directory where you installed Second Life (eg, cd /usr/bin/SecondLife ) and hit return.
3 - Type "cp ", space, followed by the full pathname of the Cool Viewer file you downloaded, followed by a space, and a dot, then return (eg, cp /home/user/downloads/CoolViewer . ). Note that you normally have to type the whole name of the CoolViewer file, complete with the - and all the numbers, but you might be able to save yourself this by pressing the TAB key after typing "CoolViewer".
4 - Type "bzip2 -d ", space, followed by the name of the CoolViewer file.
5 - Type "tar xf ", space, followed by the name of the CoolViewer file but LEAVING out the .bz2 on the end (if you use the TAB method it should detect that step 2 changed the name of the file)
6 - Send an e-mail to the creator of CoolViewer asking them to at least make a Linux install package.
