IPC Installation Instructions


Installation of The Java Runtime Environment (JRE) version 1.8 is a prerequisite for IPC-2. JRE 1.8 is commonly referred to as Java 1.8, or simply Java 8. Commencing with version 2.2.6, IPC now supports both Oracle JavaSE and OpenJDK Check your java version using "java -version" command on Shell-terminal/command-prompt. If it is not present, or a version below the one specified below is installed, then please download the latest JRE (Java Runtime Environment) from your chosen provider.

Oracle JavaSE: the minimum version supported with IPC is 1.8.0_111 OpenJDK: the minimum version supported with IPC is 1.8.0_202

IPC complies with mandates to remove SSL and early versions of TLS provided that Java 1.8 or above is installed. IPC-2 will not be installed if Java version is below 1.8

If JRE has not been installed and the JRE folder is being copied (e.g. for a reference build or ‘gold’ build), then the JRE path needs to be set in the JAVA_HOME variable in /YESEFT/setenv.bat(sh) file after IPC installation.

It is a good security practice to keep your Java versions updated. Following the release of the last free Java 8 update in January 2019, you’ll need to pay a subscription fee to update your current version of Oracle Java 8. Oracle offers a free version of Java called Open JDK alongside to the paid version, but this version only works with 64 bit operating systems. Alternatively, you may wish to use Amazon’s long term free support for Java 8 using Amazon Corretto. This production ready distribution of Open JDK works on 32 bit and 64 bit operating systems and you can download it using the link below:

If you’re running a 32 bit operating system on your Point of Sale device, Worldpay will continue offering compatible IPC versions, but you must use the 32 bit version of Java from Amazon Corretto or the Oracle subscription service for Java updates.

Supported Operating Systems

IPC2 has been tested with the following operating systems:

  • Windows Embedded 8.1 Industry Pro 32 bit
  • Windows 10 Enterprise - 64 bit
  • SUSE Linux Enterprise Server 11 (x86_64)

Note: If you are using IPC as a service you need Windows Embedded 8.1 Industry Pro 32 bit.

For Windows

Please download the appropriate Windows JRE and install it. After the installation of JRE, a popup will appear to uninstall the older java version.
If there are no other applications that are dependent on the older java then uninstall the older java application (recommended). However, if other applications are dependent on the older java then follow the instructions below

  • In order to ensure availability of the older JRE path for other applications, the older JRE path needs to be added at the start of system PATH variable.
  • For information on how to set the system PATH variable please check the URL :
  • If JDK is installed then set JAVA path in system variable:

Example for System Path: C:\Java\jdk.1.8.0_144\bin

Note: MSXML4 is required if IPC will be used to print receipts directly to the printer. Download and install MSXML4 from

For Linux

Please download the appropriate Linux JRE and unzip it.

  • Run the commands below to set java path, replacing ‘JAVA_PATH’ with the location of the unzipped JRE folder.
  • sudo update-alternatives --install "/usr/bin/java" "java" "/JAVA_PATH/bin/java" 1
  • sudo update-alternatives --set java /JAVA_PATH /bin/java

IPC Installer Files

There are two installer files flavours available from IPC-2 version 2.2.6 onwards:

  • Integrated_Payment_Client_2-V2.X.X-64Bit.exe/.sh :

This will work with Java 64 bit. To use this installer, you need to install Java 64 bit Runtime Environment on your platform.

  • Integrated_Payment_Client_2-V2.X.X-32Bit.exe/.sh :

This will work with Java 32 bit. To use this installer, you need to install Java 32 bit Runtime Environment on your platform

Before installing any installer or patch verify that none of installer files has been changed.

To verify the installer, calculate the SHA-2 (SHA 512) hash value of the installer file and compare the calculated hashvalue with one which is provided in readme.txt from Worldpay.

See below diagram showing calculated Hash value. Using any Hash calculator tool hash value can be retrieved. Below is the example of ‘HashCalc’ tool, in which select .exe file from its location, select SHA512, click on calculate and tool will show you the hash value.

Note: - If hashvalue doesn't match then do not install that patch/installer and contact with Worldpay Support team. This is an essential security practice.

Installation process

  • Download the appropriate installer executable for your environment - 32-bit or 64 bit operating system.
  • The installer implements an integrity check that means IPC cannot be installed if the installer file has been modified or corrupted during download.
  • Please refer to the below installation steps to run the installer.
  • Set JAVA_HOME The installer attempts to identify the location of JRE and set JAVA_HOME for IPC appropriately. In some environments it might not be able to do.
    Please check the file below and edit it if required to set JAVA_HOME to the location of the appropriate JRE.
    Windows: my_installation_path\YESEFT\setenv.bat Linux: my_installation_path/YESEFT/
  • Once IPC is installed, please refer toIPC configurationfor IPC configuration details.
  • Run StartPOSServer.bat/sh to start the IPC application

Installation steps


  1. Run the installer and click Next.

    Note: For Windows 8.1, if the IPC Installer gets stuck for few minutes at this stage, then follow these instructions Terminate the installation process by clicking Cancel. Run the installer by executing this command in the command prompt: path\\Integrated\_Payment\_Client_2-V1.x.x.exe-Dinstall4j.nolaf=true

  2. Select your region from the dropdown list and click Next.
  3. The Installer will prompt you to select the folder for installation, defaulting to C:\YESEFT. Select a folder and click Next.

    The installation directory can be different but the folder name must always be YESEFT. For example: C:\MYPOSDIR\YESEFT.

  4. The installer will display the program name of the application (EasyVTerminal) and create a EasyVTerminal folder in start menu. Uncheck Create a Start Menu folder to avoid a shortcut in the Start Menu and click Next to continue.
  5. Click Finish to complete the setup.
