The CaWE editor is included with the Ca3DE Developers Kit, and as such requires no explicit installation: After unzipping the packed file, simply change into the CaWE sub-directory, and double-click on CaWE.exe ¹⁾.

CaWE requires some basic configuration for normal use, and thus asks you for providing at least one game (or “MOD”) configuration when it is first run:

1. 
   After clicking on OK, CaWE will automatically show you the related configuration dialog.
   
   
2. 
   Here, click on Add New for adding a new game configuration. You will then be asked for the desired name of the new config.
   
   
3. 
   You can enter anything here, i.e. normally something that reminds you what MOD this config is related to, like “Ca3DE DeathMatch”.
   
   
4. Next you have to fill-in where the Game Data File is located. This is a file with .fgd suffix. One such file is already provided with the rest of the Ca3DE Developer Kit: the DeathMatch.fgd file in the Ca3D-Engine/Games/DeathMatch subdirectory. Click on the related Browse… button and locate the file.
   
   
5. 
   Finally, fill-in the rest of the dialog appropriately such that it eventually looks like this. The paths will of course be different for you, depending on where you installed the development kit and CaWE. Also, you do not have to provide all the settings for now, you can leave all fields with “executable” in their name empty (that is, the bottom four and the Game Executable Directory).
   
   

All settings in this dialog can be revised later at any time via the File → Configure CaWE… menu.
Adding new or additional game configurations at that time may however require to restart CaWE for the settings to take effect.

CaWE, as all other Ca3DE related software, was designed to interfere with your computer and operating system as little as possible. In general, it is enough to delete the directory that the packed file was unzipped to during installation, and all traces of CaWE are gone.

There is one exception though: When run, CaWE stores your configuration settings in a newly created directory. This directory is located in the “home” directory of the current user. The exact place on your harddisk depends on your OS and even on its version, but CaWE states the full path to it both in the Configuration dialog (General tab), and in the About dialog box that is accessible via the Help → About menu.
