If you are trying to install the Config software on a machine and are getting an error message that says:
BACstac error failed to start service: invalid state: 1
The most likely culprit is your computer's ethernet card. It could be that the software is not detecting an ethernet card at all, and hence giving the error. Plug the computer into an ethernet network (or into the Synergy controller) and attempt installation again.
This should resolve the installation problem.
