How to Install Russian and English Spell Checkers in Office 2021

Navigate to the official Microsoft download page for 'Language Accessory Packs for Office' in your web browser.

Choose 'Russian' or 'English' from the provided drop-down menu and download the correct installer version (32-bit or 64-bit) that matches your current Office installation.

Double-click the downloaded executable file and follow the on-screen prompts to install the language pack. Keep your Office applications closed during this step.

Wait for the first installation to finish completely, then repeat the process for the second language. You cannot install multiple language packs simultaneously.

Launch Microsoft Word or any other Office 2021 application and open a blank document.

Click on 'File' in the top-left corner, select 'Options' at the bottom, and navigate to the 'Language' tab in the left sidebar.

Under the 'Office authoring languages and proofing' section, ensure both Russian and English are listed. If not, click 'Add a Language' to include them.

Select your primary editing language and click 'Set as Preferred' if you want it to act as the default spell-checking dictionary for new documents.

Verify if you have administrative rights on your PC. If your Office installation is managed by an organization, manual installation will likely be blocked.

Reach out to your organization's Microsoft 365 administrator to request the addition of Russian and English proofing tools to your workstation.

Administrators can use the Office Deployment Tool (ODT) and modify the configuration.xml file to deploy multiple language packs across the network efficiently.
