Which Microsoft Office Version Works on a PC Without Internet Access?
Question details
The user needs to purchase and install an Office for Business edition on a computer that lacks continuous internet access.
- Product
- Microsoft Office
- Device & OS
- not provided
- Scenario
- Setting up business software on an offline or restricted-network workstation.
- Observed behavior
- The user requires an Office suite that remains fully functional without requiring periodic online license verification.
You will need a secondary device with an active internet connection to download the required deployment tools and installation packages before transferring them to your offline PC.
Install Office 2021 or Office LTSC for Offline Use
Use the Office Deployment Tool (ODT) to download the installation files for Office 2021 or Office LTSC and deploy them to an offline computer.
Microsoft 365 subscriptions require internet access to verify licensing every 31 days. For completely disconnected environments, businesses must use perpetual licenses like Office 2021 or Office LTSC (Long Term Servicing Channel).
On a computer with internet access, navigate to the Microsoft Download Center, download the Office Deployment Tool (ODT), and extract the files to a local folder.
Edit the extracted 'configuration.xml' file to specify the Office LTSC or Office 2021 product ID, the desired language, and the local path where the installation files will be saved.
Open Command Prompt as an administrator, navigate to the ODT folder, and run 'setup.exe /download configuration.xml' to fetch the necessary installation files to your drive.
Copy the ODT executable, the modified XML configuration file, and the newly downloaded Office installation folder to a USB drive, then transfer them to your offline PC.
On the offline PC, run 'setup.exe /configure configuration.xml' in Command Prompt to install the suite. Afterward, activate the volume-licensed installation through your local network's KMS (Key Management Service) host.
Use WPS Office for a Seamless Offline Experience
If deploying volume-licensed Microsoft Office via command-line tools seems too complex for an offline PC, WPS Office is an excellent and lightweight alternative. It offers a fully functional desktop suite that does not require continuous internet check-ins, making it perfect for disconnected workstations.
- 1. Download the Installer: Visit the official WPS Office website on a connected device and download the standard offline installer.
- 2. Transfer to Offline PC: Copy the downloaded installer file to a USB flash drive and plug it into your offline computer.
- 3. Install Offline: Run the installer on the offline PC. Once installed, you can immediately begin creating and editing documents without needing to sign in online.
Frequently Asked Questions
Can I use Microsoft 365 Apps permanently without an internet connection?
No. Microsoft 365 requires an internet connection to install, activate, and verify the subscription status at least once every 31 days. If it cannot connect within that timeframe, the applications will enter reduced functionality mode.
What is the difference between Office 2021 and Office LTSC?
Office 2021 is a perpetual license designed primarily for home users and small businesses. Office LTSC (Long Term Servicing Channel) is an enterprise-grade perpetual license designed specifically for regulated devices and manufacturing systems that cannot connect to the internet for updates.
How do I activate an offline Office installation without a KMS server?
If you do not have a Key Management Service (KMS) host on your local network, you can use a Multiple Activation Key (MAK) to activate your volume-licensed Office installation over the telephone by calling the Microsoft Activation Center.
