How to Download Volume License Serializer for MS Office

March 4, 2025 6.2K views

If you're responsible for managing MS Office installations within your organization, you may already be familiar with Volume Licensing. Volume Licensing offers a cost-effective way to manage and activate multiple Microsoft Office software across your network. It is particularly useful for businesses and institutions that need to install and activate software on a large number of computers or devices within their network.

However, it is worth noting that the Volume License Serializer facilitates the licensing process, making it more efficient and cost-effective. Unfortunately, some users don't know what Volume License Serializer is and how to download it. So, what actually is VL Serializer, and how does it work? This article will give a comprehensive review of the tool.

Volume License Serializer is a tool that activates Office LTSC for Mac 2021 or Office 2019 for Mac as a volume-licensed version. It's a package (.pkg) file that you execute on a Mac running Office. This package includes the binary executable "Microsoft Office Setup Assistant." This executable is what effectively triggers the volume license.

VL Serializer supports both Apple Silicon and Intel-based Macs natively. The volume license can be found in the file /Library/Preferences/com.microsoft.office.licensingV2.plist. The VL Serializer's license plist contains data that has been encrypted using the serial number of the boot drive on the device where it was generated. The plist is decrypted upon each Office application launch using the current boot drive serial number as the decryption key.

If the data cannot be decrypted (for example, the boot drive serial number is different), MS Office will automatically become unlicensed. Because the licensing plist file is encrypted with information from the device on which it is installed, you cannot copy it to another device to activate Office.  

There is also a single VL Serializer package with a single key shared by all volume-licensed client installations. The VL Serializer package includes the binary executable "Microsoft Office Setup Assistant." This package file is responsible for activating the volume license and is compatible with mobile device management (MDM) services like Jamf Pro and FileWave.

Here are some key features and functions of a Volume License Serializer:

  1. Centralized Activation: It allows organizations to activate software licenses centrally, reducing the need for individual activation on each computer. This is especially important when dealing with a large number of licenses.

  2. License Management: The tool helps organizations keep track of their software licenses. Thereby, ensuring compliance with licensing agreements and avoiding potential legal issues.

  3. Mass Deployment: It simplifies the process of deploying software across multiple devices or computers simultaneously. This is often done through network deployment or other automated methods.

  4. Updates and Maintenance: Some Volume License Serializers also assist in managing software updates and maintenance tasks. This ensures that all installations remain up-to-date.

  5. Reporting: Many Volume License Serializer tools provide reporting capabilities that allow administrators to generate reports on license usage, activation status, and other relevant data.

  6. Cost Savings: With VL Serializer streamlining the software license management process, organizations can potentially save money on administrative costs and reduce the risk of over-purchasing licenses.

  7. Security: In addition to the above perks, these tools often come with security features to protect license keys and ensure they are not misused or stolen.

Common examples of Volume License Serializers include tools provided by software vendors like Microsoft's Volume Activation Management Tool (VAMT) for managing Windows licenses or Adobe's Volume License Deployment (VLD) for Adobe Creative Cloud products.

Therefore, a Volume License Serializer is an essential tool for organizations looking to efficiently manage and activate multiple software licenses in a centralized manner, saving time and resources while ensuring compliance with licensing agreements.

How to Download Volume License Serializer for MS Office

Beginning with Office 2019, all perpetually licensed Office products for Windows employ Click-to-Run technology rather than the old Windows Installer technology. The Office Deployment Tool (ODT) is used to distribute eternally licensed versions of Office 2019 or later products to users in your business.

To download Office products, you'll need a broadband Internet connection with download speeds of at least 20 Mbps. It should be noted that Office products require Windows 10 or later and will not work on previous versions of Windows. With that in mind, below are the steps to download Volume License Serializer for MS Office:

Step 1: Register at the VLSC and Accept Your Software Agreement (Products with Software Assurance Only)

To begin, you'll have to register at the VLSC and accept your software license agreement if you requested discounted Microsoft items with Software Assurance.

Here's how to register at the VLSC website;

  1. Navigate to the VLSC website and click Sign In. If a sign-in screen appears, select Sign in with a Work Account.

Accessing the VLSC website


  1. Enter your organization's email address and follow the on-screen steps to create your account.

VLSC sign-in page


  1. You will receive an email in which you will be welcomed to the Volume Licensing Service Center and asked to authenticate your information. Wait 15 minutes before clicking the link in this email to validate your email address. You'll have to wait at least this long because the VLSC takes time to make the terms and conditions public.

Step 2: Get Your Office Product Key

If you requested discounted Microsoft products with Software Assurance, you'll get your product key from the VLSC site. Likewise, if you requested donated or discounted products without Software Assurance, you'll get your key through the Microsoft 365 admin center. So, follow the instructions for the products you've requested.

Here are the VLSC instructions to follow for products with software assurance;

  1. Sign in to the VLSC website and navigate to the Downloads and Keys section.

  1. Locate your Office product in the list and select the Key link.

Note: Office suites use different configuration keys for online features such as web apps. These keys are not the same as MAK product keys and cannot be used for the volume activation of desktop products.

  1. Next, copy the product's unique key from this table and paste it into a text editor like Notepad, or click Export all keys. All Volume License keys connected with agreements in your VLSC profile are outlined in this list.

Go to https://www.microsoft.com/en-us/download/details.aspx?id=49117 and click the [Download] button to download the ODT tool. After downloading, double-click to select the unzip location, you will get a red icon setup.exe and some sample xml files. All you need is the setup.exe. file.

Configuration file generated: https://config.office.com/deploymentsettings

Open the above website provided by Microsoft Office to DIY the Office you want. Below are some key points to note:

  1. Select the version with the word Volume License and not the one with the word SPLA. (Note: If you want to install Visio and other components, the LTSC version will conflict with the personal version of OFFICE. Also, if you have a personal version of OFFICE on the computer that causes installation conflicts, please do not choose the version with the word LTSC.)

  2. You are free to choose the components and languages to install, be it Word, Excel or PowerPoint.

  3. During licensing and activation, turn on the automatic acceptance of EULA and tap the KMS option.

  4. After DIY your preferred configuration, you can click the Export button. If you ask about the default file format click [Keep Current Configuration].

  5. You'll need to download a configuration file in xml format, and you can rename it to office.xml for the convenience of subsequent operations.

Step 5: Install your Favourite Office

Launching the Command prompt window


Put the setup.exe you got in step 1 and office.xml you got in step 2 in the same directory. Next, type cmd in the address bar of the current directory to open the command prompt window, after which you input the following command to execute the installation:

setup.exe /configure office.xml

You don't need to keep any large installation package and care patch. Every installation is networked to install the latest version of Office you setup. If you want to know more about ODT tools, such as using ODT to download Office, etc., you can refer to the official Microsoft documentation:
