It included with every Acquire Player and Acquire SOLO license is a free copy of our System Sentinel software (Acquire Signage2Go users may upgrade too using this service). System Sentinel acts as a guardian for your computer to protect it against even the most malicious attacks and to ensure that the system is working for you. Consider that even though the PC you are installing the software onto has been properly configured (if not, please consider our PC configuration service), once it has been installed in the remote site, any number of things can still cause an issue which may affect it and stop it from working. Unlike your desktop PC which is right in front of you, you may not be aware of the issue until many weeks later.
