If a Windows program fails to launch when you click it, some manual attention might make it see reason. Start by opening a terminal window. On Kubuntu, select System | Konsole in the start menu; if you have openSUSE, select the System | Terminals | Konsole item in the menu. Then type

cd directory

where directory represents the full path to your installation program. If the setup.exe file is on a DVD, you can access the DVD via the /media/ path. The command line looks like this:

cd /media/DVD_name

Replace DVD_name with the entry in your media directory, and then climb down the directory tree until you find the directory with the .exe file you need (in WinRAR's case, this is /programs/other/winrar). When you get there, type

wine file

replacing file with the name of the application you want to run, say, setup.exe. Make sure you stick to the exact spelling, remembering that upper- and lowercase letters are vital. To tell Wine to run the Windows program, press Enter again. If you experience difficulty launching the program, check the terminal window for error messages – you should not close the terminal window or you will terminate the Windows program running in it. If the Windows program crashes, you can try relaunching it.

The Wine MIT license gives users many privileges, a fact that has helped TransGaming generate huge profits. TransGaming just grabbed the package, added DirectX capabilities, which are required for gaming, and started to sell the results as Cedega [3] (formerly WineX). The Wine developers were unhappy about this, and thus changed the licensing terms to the LGPL in March 2002. The LGPL ensures that you can continue to use Wine for commercial purposes, but that changes and additions must be given back to the project. CodeWeavers is exemplary in this respect; the company bundled Wine with its own commercial components to create the CrossOver [4] package, while actively promoting the ongoing development of Wine.
