To install our software, your computer should meet the specifications below. Our products have been tested using the recommended 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.

ACS Technologies recommends using a tray-fed laser or inkjet printer that is compatible with the system requirements provided above. Laser and inkjet printers are also suitable if driver support is available for the associated operating system.


The MICR Image Reader works only with the desktop version of ACS.


For all software, ACS Technologies recommends using 17-inch monitors, which are designed at 96 dpi. Widescreen monitors may cause some software to look different on a 17-inch monitor, unless dpi settings are modified.


As ACS Technologies moves more products and services to the Web, we recommend a high speed internet connection using the latest, stable version of Microsoft Internet Explorer®, Chrome®, Safari®, or Firefox®.

While an internet connection is not required for using the basic features of the ACS desktop products, some are not available without an internet connection. These features include, but are not limited to, the following products and functions:

  • Access ACS™
  • Facility Scheduler
  • ACS Sync
  • ACS LiveStor™ 
  • CASS It\!/MAX It\!®
  • Sending E-mails via Constant Contact

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, ACS Technologies recommends 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.
