How to Deploy UnRAR Across Multiple Workstations

Deploying UnRAR across an enterprise fleet requires centralized management to ensure consistent, secure, and automated installation without user interruption. This guide outlines the most efficient methods for deploying UnRAR across Windows, macOS, and Linux environments, focusing on enterprise deployment platforms like Microsoft Intune, MECM, configuration management frameworks, and native package managers.

Windows Enterprise Deployment

The standard enterprise approach for Windows systems involves packaging the binary or installer for distribution via Mobile Device Management (MDM) or systems management platforms.

Method 1: Microsoft Intune (Win32 App)

The modern standard for cloud-managed endpoints is packaging the installer as an .intunewin file.

  1. Prepare the Source Files: Download the official UnRAR command-line binary or the standard WinRAR installer from RARLab. If deploying just unrar.exe, place it in a source folder alongside a deployment script (such as PowerShell).
  2. Create the Package: Use the Microsoft Win32 Content Prep Tool (IntuneWinAppUtil.exe) to package the source directory.
  3. Configure Install Commands:
    • Full Installer: winrar-x64-xxx.exe /S (the /S flag executes a completely silent installation).
    • Standalone Binary Deployment: Use a PowerShell script to copy unrar.exe to a system path (e.g., C:\Program Files\UnRAR\) and add that directory to the system PATH environment variable.
  4. Detection Rules: Set a file-based detection rule verifying the existence of unrar.exe in the target directory, or check the uninstall registry key if using the full installer.
  5. Assign: Deploy to target device groups using a phased rollout.

Method 2: Microsoft Endpoint Configuration Manager (MECM / SCCM)

For on-premises environments, MECM provides robust control via Applications or Packages.

  • Create a new Application and select Script Installer.
  • Set the installation program to winrar-x64-xxx.exe /S.
  • Configure the uninstall command as "%ProgramFiles%\WinRAR\uninstall.exe" /S.
  • Set user experience settings to install for the system and run whether or not a user is logged on.

Method 3: Windows Package Manager (Winget) or Chocolatey

For lightweight automation via existing RMM (Remote Monitoring and Management) tools:

  • Winget Script: Run winget install --id RARLab.WinRAR --silent --accept-source-agreements --accept-package-agreements via administrative script.
  • Chocolatey (for Business): Host an internal package and execute choco install unrar -y across target fleets.

Linux and macOS Deployment

Deploying UnRAR to non-Windows workstations is best handled through native configuration management or operating system packaging.

Linux (Ubuntu, Debian, RHEL, Fedora)

Use configuration management platforms like Ansible, Puppet, or SaltStack to deploy UnRAR natively across your inventory.

Ansible Playbook Example:

- name: Install UnRAR across workstations
  hosts: workstations
  become: yes
  tasks:
    - name: Install unrar on Debian/Ubuntu
      apt:
        name: unrar
        state: present
        update_cache: yes
      when: ansible_os_family == "Debian"

    - name: Install unrar on RHEL/CentOS/Fedora
      dnf:
        name: unrar
        state: present
      when: ansible_os_family == "RedHat"

macOS (Jamf Pro, Kandji, Munki)

  • Custom PKG: Package the macOS unrar binary into a signed standard .pkg using tools like pkgbuild, placing it in /usr/local/bin or /opt/homebrew/bin, and deploy via your MDM.
  • Homebrew Script: If workstations utilize managed Homebrew installations, trigger an automated script: brew install unrar.

Best Practices for Enterprise Rollouts

  • Verify Licensing: UnRAR’s command-line source and binary have specific licensing terms distinct from GNU software. If deploying the full WinRAR GUI package, ensure adequate volume licenses are procured and applied silently by copying the rarreg.key to the installation folder during installation.
  • Standardize File Paths: Ensure unrar.exe is added to the system's PATH variable so command-line utilities and scripts can invoke it without requiring hardcoded absolute paths.
  • Staged Rollouts: Deploy to a pilot group first to ensure silent switches function properly and do not trigger endpoint detection and response (EDR) heuristics.
