There are 3 different packages available for download: Linux, Mac and Windows
The Windows archive is the only one containing a bundled JRE and libraries for convenience - this allows to run Chronomotion without actually installing anything.
Mac and Linux users are expected to be capable of installing JAVE Runtime Environment (JRE) and libraries (RXTX library) on their own - see below.
A version that comes bundled with JRE and the RXTX DLL can be run without any installation or additional downloads.
To see error messages and reports of what is missing/not working be sure to run the software from commandline/terminal/console rather than just double clicking on it.
If you are not happy with the provided bundled Win32 package and you want to use run Chronomotion in 64bit you need both a Java 64Bit JRE and the RXTX 64bit DLLs. The official rxtx builds contain no Windows 64Bit DLLS. But there are people providing these on their own website, like: http://www.cloudhopper.com/opensource/rxtx/
Just download and put the DLLS into the same directory as your Chronomotion files.
No trouble reported so far
If you receive the error
serial port already in use
when starting Chronomotion try to execute the following in console/terminal:
sudo mkdir /var/lock sudo chmod a+rw /var/lock
