- Product
- Microsoft Office 2021 Home and Business
- Device & OS
- not provided
- Scenario
- Preparing for a future offline reinstallation of Office 2021, particularly in situations with limited or no internet access.
- Observed behavior
- Standard Office installations run as an online stream and do not leave a standalone installation package on the local drive for future offline use.
Ensure you have an active Microsoft account linked to your Office 2021 purchase and a stable internet connection for the initial download of the large offline installer package.
Use the Official Microsoft Office Offline Installer
This is the official and recommended method to get the standalone installation files for Office 2021.
By default, Microsoft uses a Click-to-Run online installer that streams files directly. To install Office without the internet, you must manually select the offline installer option from your Microsoft account.
Go to account.microsoft.com and sign in with the Microsoft account associated with your Office 2021 Home and Business purchase.
Click on 'Services & subscriptions' in the top menu to view the list of products linked to your account.
Locate your Office 2021 Home and Business product in the list and click the 'Install' button next to it.
In the Download and install pop-up window, select 'Other options'. Check the box for 'Download an offline installer', choose your preferred language, and click 'Download'.
Once the image file (.img or .iso) is fully downloaded, save it to an external drive. To install offline later, double-click the file to mount it as a virtual drive and run the 'Setup.exe' file.
Install via Microsoft Support and Recovery Assistant
If you are experiencing slow or unreliable internet connections that interrupt the standard installer, this diagnostic tool can help manage the installation process.
Try WPS Office for a Fast, Lightweight, and Free Installation

- 1. Visit the Official Website: Go to the official WPS Office website.
- 2. Download the Installer: Click the 'Free Download' button to get the lightweight offline installer.
- 3. Install WPS Office: Run the downloaded executable file to quickly install the software and start editing documents.
Frequently Asked Questions
Can I use Microsoft Office offline after installation?
Yes. Once Office 2021 is fully installed and activated (which requires a one-time internet connection), you can create, edit, and save documents offline without needing an active internet connection.
Where are the default Office installation files stored?
By default, the Click-to-Run online installer does not save a standalone installation package on your local drive. The files are streamed and immediately unpacked into hidden system folders, which is why you must manually download an offline installer for offline reinstallation.
Can I simply copy my installed Office files to another computer?
No, copying the installed directory folder to another PC will not work because Microsoft Office requires specific registry entries, system file configurations, and software activation records. You must use the standalone offline installer package to install it properly on another machine.
