System requirements

Operating system

The operating system must be fully installed and configured with the latest service packs and hot fixes. Single store installations (Store Manager, POS, and Store Loyalty) are compatible with a 32-bit operating system. However, multi-store installations (Central Manager, Central Client, Central Server, Flash Bridge, Store Manager, POS, and Central Loyalty) require a 64-bit operating system and are not compatible with a 32-bit operating system.

Windows 11 (Professional)
Windows 10 (Professional or Enterprise)

Windows Server 2022
Windows Server 2019

Warning! Although RMH apps have been known to work on Windows 10/11 (Home), the Home version of the Windows operating system is not recommended for running production workloads. In addition, Windows 10/11 Home is not recommended for hosting Microsoft SQL Server.

Microsoft SQL Server

The SQL Server must be fully installed and configured with the latest service packs and hot fixes.

Microsoft SQL Server 2022 Standard (Recommended)
Microsoft SQL Server 2019 Standard
Microsoft SQL Server 2022 Express
Microsoft SQL Server 2019 Express

Note: Microsoft SQL Server Standard is required for databases that are 10GB or larger. Ensure firewall ports have been configured to allow TCP/IP traffic from Microsoft SQL Server.

Hardware

You will need to increase memory as database size increases. These are the requirements for Retail Management Hero only; consider the resource requirements of all applications on the computer and increase memory and processor power accordingly.

Other system requirements

Application	Requirement
POS	POS for .NET Note: POS for .NET is different from the .NET Framework. It is a library that enables communication between OPOS devices like electronic cash drawers, printers, scanners, and scales. You can install POS for .NET from the installation wizard (Setup.exe).
POS, Store Manager, Central Manager, Central Server, Central Client, and Flash Bridge apps	.NET Framework 6.0 Install the following: ASP.NET Core Runtime 6.0 (Windows x64) .NET Desktop Runtime 6.0 (Windows x64) Alternately, install the .NET SDK (Windows x64), which provides all runtimes in one download package.
All Central Manager deployments	RMH Central should only be deployed in environments with internal connectivity across the stores. This can be accomplished either by a virtual private network (VPN) or by any other intranet solution offered through your Internet Service Provider (ISP). Note: The Flash-based Central Manager and Central Client also require a route to the internet for license validation. If you need to run these apps in environments where internet access is restricted, you should deploy an internal license server.
