2: After clickng OK on both dialogs, click Search and type in unshield. It will show three packages, just double click on unshield and it will ask you if you also want to mark libunshield, which is required. Click mark, then cick Apply. Unshield is required by the installer.
3: After downloading the script http://www.paradoxinc.net/~icarus/files/install-nwn.sh right click on it and select properties. Then select the Permissions tab. On the Owner line, put a check in Execute. Click close.
4: Double click on the install-nwn.sh and select Run in Terminal.
5: A terminal window will open, asking if you're installing the CD or DVD version. Select the proper one, then enter. Then it asks for the cdrom path. On Ubuntu, this will be /media/cdrom for the first drive. Next is the install directory. By default this is /usr/local/games/nwn. Change this if you'd like. If you're going to install there, you will need to use sudo. If you don't have multiple people using your computer, then just put it in /home/<username>/nwn. Next it asks for the current patch version that is located in the users home directory (1.66 is the newest patch). Note, if you haven't downloaded the patch (English_linuxclient166_xp2.tar.gz) then it will ask you if you wish to download it.
Important: When the script asks "Do you wish for the script to mount the CD (Y/n)" you'll want to choose NO. This is because Ubuntu will automatically mount the CDs for you when you insert them. For the group, it is safe enough to just hit enter (since you should already be in the users group.)
Last but not least, start inserting the CDs. It starts off with disk 2. (Hint: You'll know when to hit enter on the script, because Nautilus will open up a window showing what is on the CD/DVD you just entered. This shows that it is mounted and the script can do it's thing) To eject a CD/DVD, right click on the icon on the desktop and select eject.
6: There is no step number 6
7: After installation, if you want an icon either on the desktop or on the menu you will need to edit the nwn start up script. Just 'gedit ~/nwn/nwn' and add under the line 'cd /home/<username>/nwn' (without the 's)
7a: For a desktop Icon, simply right click on the desktop, and select Create Launcher. Enter the Name (Neverwinter Nights), You don't really need Generic name or Comment. For the command you can either Browse to /home/<username>/nwn and select the nwn file. For the Icon, you can click on the button that says No Icon, and then browse to /home/<username>/nwn and select nwn.ico.
# This script runs Neverwinter Nights from the current directory
7b: For a menu entry. Select Applications -> System Toos -> Applications Menu Editor. Then in the left hand column, select Games. Then press the New Entry button. The rest is exactly like installing the desktop Launcher above. Then quit the Menu Editor and you will have a Neverwinter Nights menu entry under Applications -> Games.
8: Now load the game up. After the initial boot screen, you will be asked for the CD-Keys. They are printed inside the front cover of your manual. You will have to enter the key for the Original Neverwinter Nights twice. I have no idea why, but it asks for it twice. The others are only required once.
That concludes the Nwn how to for now. I may (if I have time, which I seem to lately, since I have been laid off for two weeks now) I will clean this up, include screenshots and also add n how to get the Movies to play as well.
Hope this is helpful.
