System Requirements

To install our software, your computer should meet the specifications below. 

Our products have been tested using the system requirements on this page. However, because computing environments and internet service vary so widely, these system requirements are provided without guarantee. Your computer performance will vary based on hardware configurations, network traffic, and local workstation settings.

Microsoft End of Life Policy

ACS Technologies adheres to Microsoft's life-cycle policy for operating systems.

As a system approaches its end-of-life date, we recommend upgrading your operating system. Once an operating system is no longer supported by Microsoft, we can no longer support that system. This does not mean that products will not work on a retired operating system, but it does mean that, should a problem occur that would require an update for a retired operating system, we cannot provide support assistance for clients using those operating systems.
