Step 1: Access the Office Configuration Tool

Open your browser and search for Office Config.
Visit the official Microsoft website at config.office.com.
Scroll down and select Create a new configuration file.

Step 2: Configure Your Office Suite

Choose Architecture:
- To check your system’s architecture, type System Information in the Windows search bar.
- Look for System Type to see if it’s 32-bit or 64-bit. For this guide, we’ll use 64-bit (recommended for modern systems).
- Select 64-bit in the configuration tool.
Select Office Suite:
- Choose the Office version you want (e.g., Office 2019, 2021, 2024, or Office 365).
- For this guide, select Office 2024 LTSC Professional Plus.
Optional Apps:
- You can include Project Professional 2024 or Visio Professional 2024 if needed. For this guide, we’ll skip these.
Update Channel:
- Leave the default settings unchanged.
Apps Selection:
- Uncheck apps you don’t want to install (e.g., OneDrive, Outlook, Skype for Business).
Language:
- Select English (United States) or your preferred language.
Installation Settings:
- Keep all default options.
Update and Upgrade:
- Ensure Uninstall any previous versions of Office is checked.
- Keep other settings as default.
Click Next, then Next again, and finally Finish.

Step 3: Export the Configuration File

Click Export.
Choose Office XML format.
Read and comply with the terms and conditions.
Name your XML file (e.g., Office2024Config.xml) and click Export.

Step 4: Download the Office Deployment Tool

In a new tab, search for Office Deployment Tool.
Visit the official Microsoft link and download the tool.
You should now have two files in your Downloads folder: the XML configuration file and the Office Deployment Tool.

Step 5: Set Up Files

Create a new folder on your Desktop (e.g., OfficeInstaller).
Move the XML file and Office Deployment Tool to this folder.
For clarity, enable View file extensions in File Explorer:
- Go to File Explorer > View > Options > Uncheck "Hide extensions for known file types".
Run the Office Deployment Tool and extract its contents to the new folder.
Delete unnecessary files, keeping only:
- setup.exe
- Your XML configuration file (e.g., Office2024Config.xml).

Step 6: Download the Offline Installer

Search for Office Deployment Tool commands and visit the official Microsoft support page.
Find the section Download the installation files for Microsoft 365 Apps.
Copy the provided download command.
Create a new text file in your folder (e.g., commands.txt) and paste the command.
Replace the default XML filename in the command with your XML file name (e.g., Office2024Config.xml).

Example command:
```
setup.exe /download Office2024Config.xml
```
Open Command Prompt (CMD) as Administrator:
- Search for CMD in the Windows search bar, right-click, and select Run as Administrator.
Copy the folder path of your OfficeInstaller folder.
In CMD, type cd, add a space, paste the folder path, and press Enter.
Copy the download command from your text file, paste it into CMD, and press Enter.
Monitor Task Manager (Ctrl+Shift+Esc) for network activity to confirm the download has started. Ensure a stable internet connection.
Once complete, check the OfficeInstaller folder. You’ll find an Office folder containing a Data folder, with a subfolder named with a version number starting with 16 (e.g., 16.x.x.x). This contains the offline installer files.

Step 7: Share the Offline Package (Optional)

Create a ZIP or RAR archive of the OfficeInstaller folder.
Transfer the archive to another computer and extract it to the Desktop.

Step 8: Install Office Offline

On the target computer, open CMD as Administrator.
Navigate to the extracted folder using the cd command and the folder path.
On the Microsoft support page, find the Office 365 installation apps section and copy the install command.
Paste it into your text file and replace the XML filename with your own (e.g., Office2024Config.xml).

Example command:
```
setup.exe /configure Office2024Config.xml
```
Copy the command, paste it into CMD, and press Enter.
Monitor Task Manager. There should be no network activity, confirming the installation is offline.

Step 9: Verify Installation

Once installation is complete, open Office apps (e.g., Word, Excel) to confirm they work correctly.
All selected apps should be installed and functional.

Conclusion

You’ve successfully downloaded and installed Microsoft Office 2024 LTSC using the official offline installer. This method ensures a safe and reliable setup without relying on third-party sources.
