First, just like in windows, you've gotta know where you downloaded the client. It'll probably be in your home directory somewhere, and most of the time you'll have an icon that says "home" or something on the desktop, so you can click on that and then poke around in there until you've found it. Once you find it open up a terminal window. If it's in some sub-folder of your home directory you can use the command cd to move into directories until you get there. Also, the command ls will list the files in a directory in case you want to see what's in it. One thing that throws a lot of people off when they first try Linux is how the file permissions work. In linux, there are a set of permissions that determine whether or not the file can be read, whether or not the file can be written to, and whether or not the file can be executed. Just because you download something that ends in .exe doesn't mean the OS will let you execute it as is. You've got to flip on the execute permissions in order to run it. You do that with the chmod command
chmod +x FAH502-Linux.exe
chmod 755 FAH502-Linux.exe
If you want to try the old school way. /cool.gif' border='0' style='vertical-align:middle' alt='cool.gif' />
I'm sure there's some way to do this through the GUI, but I've never really bothered to look for it. After you've got the permissions set up you should be able to run it from the GUI, or type in the path to it and run it from the command line.
Do not meddle in the affairs of archers, for they are subtle and quick to anger.
