An overview of enabling Launcher PCB Mode and, when needed, adding a Windows Registry installation-path override.<\/p>\n

Installing Epic Games Launcher and Unreal Engine on multiple computers can be time-consuming and difficult to maintain, especially for IT staff and developers responsible for dozens or hundreds of computers in schools, offices, or internet cafes. Launcher features described here simplify installation and updating of applications such as Unreal Engine 4 (UE4). This overview explains how to deploy the Launcher to multiple computers so applications are easier to set up and maintain.<\/p>\n

By the end of this document, you will know how to enable\u00a0\u00a0Launcher PCB Mode<\/strong>\u00a0\u00a0and, if needed, configure a\u00a0\u00a0Windows Registry Install Path Override<\/strong>\u00a0\u00a0after enabling PCB Mode.<\/p>\n

Launcher PCB Mode<\/h2>\n

On Windows, the Launcher normally stores manifest, dynamic, and temporary files in the system folder\u00a0ProgramData<\/strong>%programdata%\\Epic<\/code>\u00a0(for example,\u00a0C:\\ProgramData\\Epic<\/code>). If an office, school, or internet-cafe administrator installs the Launcher and Unreal Engine on a server without copying the program data to client machines, installation problems may occur. A client may be unable to find installed games or may attempt to reinstall applications.<\/p>\n

System administrators may otherwise need a complicated process to mirror the ProgramData folder across client machines. To simplify this workflow, the Launcher supports\u00a0PCB Mode<\/strong>\u00a0. When PCB Mode is enabled, the Launcher stores the program-data folder inside its installation directory. For example, internet-cafe owners can configure the Launcher on a server once and copy its installation folder to clients. With the program data in the installation folder, no separate copying process is needed.<\/p>\n

If you have not installed UE4 before, read the introductory guide covering the basics of\u00a0\u00a0Installing Unreal Engine<\/a>\u00a0.<\/p>\n<\/div>\n

Enabling Launcher PCB Mode<\/h3>\n

Follow these steps to enable Launcher PCB Mode:<\/p>\n

    \n
  1. \n

    Install the Launcher on at least one machine, which may be a server. This guide calls it the \u201coriginal computer\u201d.<\/p>\n<\/li>\n

  2. \n

    Close the Launcher before continuing.<\/p>\n<\/li>\n

  3. \n

    To enable\u00a0Launcher PCB Mode<\/strong>\u00a0, move or copy the folder\u00a0Epic<\/strong>\u00a0into the Launcher installation directory. In this example, the Epic folder is moved from\u00a0C:\\ProgramData\\Epic<\/code>to\u00a0C:\\Program Files (x86)\\Epic Games\\Launcher<\/code>.<\/p>\n<\/li>\n<\/ol>\n

    1. Use the Launcher to install the engine versions you want on the new computers.<\/li>\n
    2. Finally, copy the Launcher and engine installation directories to the new computers.<\/li>\n<\/ol>\n

      If a new computer has a different engine installation path or different drive letters from the original computer, add a\u00a0Registry Install Path Override<\/strong>\u00a0after enabling Launcher PCB Mode.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

      Disabling Launcher PCB Mode<\/h3>\n

      To disable this mode, close the Launcher and move the folder\u00a0Epic<\/strong>\u00a0from the Launcher installation directory back to\u00a0ProgramData<\/strong>\u00a0. Restart the Launcher after moving it.<\/p>\n

      Windows Registry Install Path Override<\/h2>\n

      The Launcher stores game and application installation locations in manifest files in the\u00a0system ProgramData folder.\u00a0<\/strong>In the behavior described here, moving an installed game or application prevents the Launcher from detecting that installation. This matters when copying the Launcher and its games or applications to machines with different drive letters or directory layouts. If moved or copied installations cannot be found, a Registry Install Path Override can point to the new game or application folder.<\/p>\n
