Introduction

Microsoft Office has remained one of the world's most trusted productivity solutions for decades. From students and professionals to businesses and organizations, millions of users depend on Microsoft Office applications for creating documents, analyzing data, preparing presentations, managing emails, and completing daily productivity tasks.

With newer versions like Microsoft Office 2024 and subscription-based Microsoft 365 available, many users are asking an important question:

Is Microsoft Office 2021 still worth buying in 2026 before support ends?

Microsoft Office 2021 Professional Plus, Home & Business, and other editions continue to provide powerful desktop applications with a traditional one-time purchase license. Unlike Microsoft 365, which requires monthly or yearly payments, Office 2021 allows users to purchase the software once and continue using the installed applications without recurring subscription costs.

Office 2021 remains popular because it provides essential applications such as:

• Microsoft Word 2021
• Microsoft Excel 2021
• Microsoft PowerPoint 2021
• Microsoft Outlook 2021
• Microsoft Access 2021
• Microsoft Publisher 2021

For users who prefer offline productivity, stable performance, and lifetime ownership, Office 2021 continues to be an attractive option.

What Is Microsoft Office 2021?

Microsoft Office 2021 is a standalone desktop productivity suite released by Microsoft as the successor to Office 2019.

Unlike Microsoft 365, Office 2021 follows a perpetual license model, meaning users purchase the software once and can use the installed applications without a subscription.

Office 2021 was designed for users who need:

• Professional productivity applications
• Offline access
• One-time purchase licensing
• Stable software performance
• Long-term usability

It is available in different editions, including:

Is Microsoft Office 2021 Still Supported in 2026?

One of the most important factors before purchasing Office 2021 is understanding its support lifecycle.

Microsoft Office 2021 follows Microsoft's fixed lifecycle policy.

During the support period, users receive:

• Security updates
• Bug fixes
• Stability improvements

However, Office 2021 does not receive:

• Major new features
• Continuous improvements
• AI-powered upgrades available in Microsoft 365

Users considering Office 2021 in 2026 should evaluate how long they plan to use the software.

For users who need basic productivity applications, Office 2021 can still provide excellent value.

For businesses requiring the latest features and cloud collaboration, newer versions may be more suitable.

Installing Office LTSC 2024 through the Office Deployment Tool (ODT) gives IT administrators greater control over the installation architecture, language, product edition, installation source, and deployment process. Microsoft provides ODT specifically for configuring and deploying Office LTSC 2024, including the ability to download the complete installation files to a local computer or network share and install Office later without repeatedly downloading the files.

The process consists of four main stages:

1. Download the latest Office Deployment Tool.
2. Create an appropriate configuration.xml file.
3. Download the Office LTSC 2024 installation files.
4. Install Office from the downloaded local source.

Step 1: Check Your Office LTSC 2024 Requirements

Before creating an offline installer, confirm that the target computers meet Microsoft's requirements and that you have the correct Office LTSC 2024 licensing.

You should also decide:

• Which Office LTSC 2024 edition you need
• 32-bit or 64-bit architecture
• Installation language
• Whether previous Office versions should be removed
• Where the offline installation files will be stored
• Whether multiple computers will use the same installation source
• How Office will be activated after installation

For most modern Windows environments, administrators commonly evaluate the 64-bit edition, but application and add-in compatibility should be checked before deployment.

Step 2: Download the Office Deployment Tool

The Office Deployment Tool (ODT) is Microsoft's command-line deployment utility for Office. Microsoft recommends downloading the latest ODT version from the official Microsoft Download Center.

Create a working folder such as:

C:\OfficeLTSC2024

Download the ODT executable and run it.

When prompted for an extraction location, select your working folder.

After extraction, you should have files similar to:

C:\OfficeLTSC2024

│

├── setup.exe

└── configuration.xml

The setup.exe file is the Office Deployment Tool, while the XML file controls the download and installation configuration.

Step 3: Create the Configuration XML File

The configuration.xml file tells ODT what Office product to download or install.

You can create the file using Notepad or Microsoft's Office Customization Tool. Microsoft recommends the Office Customization Tool as a convenient way to create and customize ODT configuration files.

For a basic 64-bit English installation of Office LTSC Professional Plus 2024, use:

<Configuration>

  <Add OfficeClientEdition="64" Channel="PerpetualVL2024">

    <Product ID="ProPlus2024Volume">

      <Language ID="en-us" />

    </Product>

  </Add>

</Configuration>

Understanding the Configuration

The important settings are:

OfficeClientEdition="64"
Specifies the 64-bit Office installation.

Channel="PerpetualVL2024"
Specifies the Office LTSC 2024 perpetual volume-license channel.

Product ID="ProPlus2024Volume"
Specifies Office LTSC Professional Plus 2024.

Language ID="en-us"
Specifies English (United States).

Microsoft lists ProPlus2024Volume as the Product ID for Office LTSC Professional Plus 2024. Other supported volume products have their own Product IDs.

Step 4: Choose a Local Source for the Offline Installer

If you want to create a reusable offline installation package, you can specify a SourcePath.

For example:

<Configuration>

  <Add OfficeClientEdition="64"

       Channel="PerpetualVL2024"

       SourcePath="C:\OfficeLTSC2024\OfficeFiles">

    <Product ID="ProPlus2024Volume">

      <Language ID="en-us" />

    </Product>

  </Add>

</Configuration>

For an organization's shared network location, the source can instead point to a network share:

SourcePath="\\Server\OfficeShare"

Microsoft supports downloading Office LTSC 2024 files to a local network location and then using that location as the installation source.

Step 5: Open Command Prompt as Administrator

After saving the XML configuration, open Command Prompt with Administrator privileges.

Navigate to your ODT folder:

cd /d C:\OfficeLTSC2024

You should now be working from the directory containing setup.exe and your configuration file.

Step 6: Download the Office LTSC 2024 Offline Installation Files

Run:

setup.exe /download configuration.xml

This tells ODT to download the Office LTSC 2024 installation files according to the settings in your XML file.

The command may appear to do nothing while the files are being downloaded. Microsoft notes that the download occurs in the background, and the command prompt returns after the download is complete.

Depending on your SourcePath, the downloaded files will be stored in the specified location.

A typical structure may look similar to:

C:\OfficeLTSC2024

│

├── setup.exe

├── configuration.xml

│

└── Office

    └── Data

        └── 16.0.xxxxx.xxxxx

The exact version folder and files can vary.

Step 7: Verify the Offline Download

Before installing Office, verify that the Office files were successfully downloaded.

Check the configured source directory and look for an Office\Data structure.

For example:

Office

└── Data

    └── 16.0.xxxxx.xxxxx

If the folder contains the required Office installation data, the offline installation source is ready.

Microsoft notes that the downloaded files vary according to the selected architecture and languages.

Step 8: Transfer the Offline Installer to Another Computer

One of the main advantages of this method is that the downloaded Office files can be stored on a local network share or other approved deployment storage.

For example:

\\Server\OfficeLTSC2024

The administrator can then make the source available to other authorized computers on the organization's network.

This is particularly useful when multiple computers need the same Office LTSC 2024 installation and administrators want to avoid downloading the same installation content repeatedly.

Step 9: Install Office LTSC 2024 From the Offline Source

On the target Windows computer, open Command Prompt as Administrator.

Navigate to the folder containing the ODT setup.exe and configuration file.

Then run:

setup.exe /configure configuration.xml

ODT will read the configuration file and install Office LTSC 2024 according to the specified settings.

If the configuration points to a local or network SourcePath, ODT can use the downloaded installation files instead of downloading the entire Office package again.

Step 10: Install From a Network Share

For organizations deploying Office to multiple computers, a network share can be used as the installation source.

For example:

<Configuration>

  <Add OfficeClientEdition="64"

       Channel="PerpetualVL2024"

       SourcePath="\\Server\OfficeLTSC2024">

    <Product ID="ProPlus2024Volume">

      <Language ID="en-us" />

    </Product>

  </Add>

</Configuration>

Then run:

setup.exe /configure configuration.xml

This approach allows multiple authorized computers to access a centralized Office installation source. Microsoft specifically documents local-network deployment as an option for Office LTSC 2024.

Step 11: Remove Older Office Versions Before Installation

If the computer contains an older Office installation, it is important to plan how it will be removed before deploying Office LTSC 2024.

For older MSI-based Office installations, Microsoft recommends using the RemoveMSI element.

Example:

<Configuration>

  <Add OfficeClientEdition="64" Channel="PerpetualVL2024">

    <Product ID="ProPlus2024Volume">

      <Language ID="en-us" />

    </Product>

  </Add>



  <RemoveMSI />

</Configuration>

Microsoft explains that RemoveMSI can remove applicable older MSI-based Office, Visio, and Project installations. For older Click-to-Run versions such as Office 2019, a different Remove configuration may be required.

Step 12: Customize the Installation

The XML configuration can be expanded according to your organization's deployment requirements.

For example, administrators can configure:

• Office architecture
• Office product
• Display language
• Proofing tools
• Installation source
• Previous Office removal
• Update settings
• Installation display options

A more controlled configuration might look like:

<Configuration>

  <Add OfficeClientEdition="64"

       Channel="PerpetualVL2024"

       SourcePath="C:\OfficeLTSC2024\OfficeFiles">



    <Product ID="ProPlus2024Volume">

      <Language ID="en-us" />

    </Product>



  </Add>



  <RemoveMSI />



  <Display Level="None" AcceptEULA="TRUE" />

</Configuration>

Test customized XML configurations on a small group of computers before deploying them throughout an organization.

Step 13: Install Additional Languages

Office LTSC 2024 can be deployed with additional language packs and proofing tools through the ODT configuration file.

For example:

<Product ID="ProPlus2024Volume">

  <Language ID="en-us" />

  <Language ID="fr-fr" />

</Product>

Microsoft also supports the ProofingTools Product ID for deploying proofing tools separately when users need additional language support without installing the complete Office interface in that language.

Step 14: Verify the Installation

After installation finishes, open an Office application such as Word or Excel.

Go to:

File → Account

Check the displayed Office product information.

You should verify that:

• The correct Office edition is installed.
• The expected applications are available.
• The correct architecture was deployed.
• The expected language is installed.
• The installation completed without errors.

Activation should then be completed using the organization's legitimate volume-licensing method.

Step 15: Activate Office LTSC 2024

Downloading and installing Office LTSC 2024 does not replace the licensing process.

Organizations using volume licensing can use supported activation methods such as KMS, MAK, or Active Directory-based activation, depending on their licensing and infrastructure. Microsoft maintains separate documentation for these activation methods.

Do not use unofficial activators, cracks, unauthorized keys, or activation bypass tools. They are not part of Microsoft's supported Office deployment process.

Step 16: Test the Offline Installation

After installation and activation, test the most important Office applications used by your organization.
