Actually Chronomotion does not need to be "installed". Just downloading and putting the right files together is enough.
A version that comes bundled with JRE and the rxtx DLL should be ready for launching 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.
rxtx library by default has no Windows 64Bit dlls.
But there are people providing these on their own website, like: http://www.cloudhopper.com/opensource/rxtx/
Just put the dlls into the same directory as your Chronomotion files.
