On a windows7 64-bit machine, there is a known issue in the 1.6.0 and later versions with the post-installer step that occasionally fails to create the executable.

UPDATE: The problem has been seen also with the 2.0.0 version. It's related to the rights of the folder from which the installer is run. Running it from e.g. C:/ gives the problem, even when it's ran as Adminstrator, while executing the same installer from the default user's Downloads folder (C:/Users/<username>/Downloads) works ok.

If that still would fail:

You can still run the ConfigFileEditor by executing java -jar jar/coupe.jar from the install directory or doubleclick the coupe.jar executable jar located in the jar subfolder of the install directory.
