# Software Requirements

## Software Requirements

Software requirements are applications, drivers or libraries which may not be included with the operating system by default.

***

### Microsoft .NET Framework 3.5 or later

Microsoft .NET framework 3.5 is included with the Maitre'D installation program. It will be installed automatically if the Install Shield Wizard does not detect it on your system.

***

### Microsoft Windows Installer 4.5 or later

Windows 10 already has a more recent version of Windows Installer, but version 4.5 is still supplied with the Maitre'D installation program in case there is a need to install Maitre'D on an earlier operating system which could have an earlier version of Windows Installer.

***

### Java for Windows (formerly Java Runtime Environment (JRE))

While it is optional for Maitre'D itself, Java for Windows is required with some Electronic Funds Transfer (EFT) payment solutions like SecureTable and SecurePay. This is also often required by third-party vendors for specific applications. This component needs to be downloaded and installed manually from the Java website.

It can be downloaded and installed from here: <https://www.java.com/en/>

***

### Microsoft Internet Explorer 11 or later

For operating systems prior to Windows 10, this would be supplied through Windows Updates. Since Windows 10, Internet Explorer is bundled with the operating system. It does not need to be the default browser.

***

### All available Windows Updates for your operating system

Your operating system needs to be kept up-to-date with all the latest updates. This will ensure that all critical and security-related updates are installed and will help maintain PCI-DSS compliance.

***

### Anti-Virus / Anti-Malware

Install a reputable anti-virus and anti-malware solution on the PC. The Anti-Virus / Anti-Malware solution needs to be fully operational at all times and maintained with the latest updates and virus definitions. PayFacto does not recommend any brand in particular. However, while Microsoft's Windows Defender solution is free, bundled with Windows and works in most cases, we do recommend using a reputable, independently branded and well reviewed product.

This is a critical component of the Maitre’D system’s security and a requirement for PCI-DSS compliance.

***

### Firewall

In addition to the perimeter firewall which protects your network, a software firewall needs to be installed on the main Back-Office PC as well as all POS workstations. The Windows Defender Firewall is adequate for most installations.

This is a critical component of the Maitre’D system’s security and a requirement for PCI-DSS compliance.
