How can I debug my controller install?
The Controller installer actually keeps a verbose log of what it is doing on every platform. The filename is of the general format i4j_log_Controller_nnnnnnnnnnnnnnnnnnn.log.
On Linux, you can find it in the /tmp directory.
On Windows it is in the user's temp folder. (Type %TEMP% into the windows explorer location bar).
On Mac, once you start the installer, open up a terminal window and type:
lsof | grep Controller
You will see a result like this:
You can "tail -f" that filename to track the installer's detailed progress.
