MS Office 2021 Professional Plus is a current and highly sought-after office suite. It includes all essential applications for working with documents, spreadsheets, presentations, and email. To fully utilize the benefits of licensed software, it’s important to properly download and install it from a reliable source.

Key Benefits of MS Office 2021 Professional Plus

Before you purchase and download MS Office 2021 Professional Plus we recommend reviewing the suite’s capabilities and system requirements. Key applications in the suite include:

• Word — a multifunctional word processor featuring powerful formatting tools, spell check, and collaborative editing and review capabilities for documents
• Excel — a spreadsheet program supporting complex formulas, analytical tools, charts, and pivot tables
• PowerPoint — a tool for creating multimedia presentations with extensive animation capabilities, audio and video embedding, and presenter modes
• Outlook — a personal information manager that combines email client functionality with calendar, address book, and task planning features

Additional Professional Plus applications include:

• Access — a flexible database management system for structured storage and processing of large data volumes
• Publisher — a convenient program for creating professionally designed publications: brochures, newsletters, business cards, and catalogs
• OneNote — a digital notebook for collecting notes, ideas, web pages, audio, video, and handwritten sketches

All applications maintain the familiar interface with tabs and ribbon menu, known since Office 2007. They seamlessly open documents created in older Office versions. The new OpenDocument 1.3 format ensures compatibility with other office suites such as LibreOffice or OpenOffice.

Additionally, Office 2021 offers numerous improvements over previous versions:

• Dark mode support for more comfortable work in low-light conditions.
• Streamlined real-time document collaboration.
• Enhanced application performance and stability.
• New chart types and data analysis functions in Excel.
• Advanced formatting capabilities in Word, including SVG text conversion.
• Modern presentation templates and animation effects in PowerPoint.
• Integration with Microsoft 365 cloud services for remote work and file storage.

System Requirements

Before installing Office 2021 Professional Plus, ensure your computer meets these minimum system requirements:

• Windows 10 or Windows 11.
• Processor with at least 1.6 GHz (8th generation Intel Core i3 or equivalent recommended).
• 4 GB RAM (8-16 GB optimal).
• 4 GB free disk space (128-256 GB SSD recommended).
• 1280×768 screen resolution (Full HD or higher optimal).
• .NET Framework 4.8.

Additionally, you’ll need to purchase a product key. Without it, Office will operate in limited mode. You can buy an activation key from Microsoft’s official website or save money by choosing a reliable online retailer offering discounted keys.

Removing Previous Office Versions

Before installing Office 2021, it’s recommended to completely remove any previously installed Office versions. This prevents conflicts and errors during installation and operation.

To uninstall Office on Windows:

1. Open Control Panel and navigate to “Programs and Features”
2. Locate the Microsoft Office version in the applications list, right-click it, and select “Uninstall”
3. Follow the uninstallation wizard prompts

If the uninstallation encounters errors or some Office components remain, you can use the Microsoft Support and Recovery Assistant utility. It automatically finds and removes all files and registry entries associated with Office.

For Mac, the removal process differs:

1. Close all Office applications.
2. Open Finder and navigate to the “Applications” folder.
3. Locate the Microsoft Office folder and move it to Trash.
4. Empty the Trash.
5. For complete removal, manually find and delete all Office-related files in the “Library” folder.

Key files and folders to remove:

• /Applications/Microsoft Word.app
• /Applications/Microsoft Excel.app
• /Applications/Microsoft PowerPoint.app
• /Applications/Microsoft Outlook.app
• /Applications/Microsoft OneNote.app
• /Applications/OneDrive.app
• /Library/Application Support/Microsoft
• /Library/Fonts/Microsoft
• /Library/Preferences/com.microsoft.⋅
• ~/Library/Application Support/Microsoft
• ~/Library/Containers/com.microsoft.⋅
• ~/Library/Group Containers/UBF8T346G9.ms
• ~/Library/Preferences/com.microsoft.⋅

After removal, restart your computer to complete the process and free up system resources previously used by the applications.

Downloading Office 2021 Professional Plus

The most reliable and secure way to obtain an Office 2021 license is through Microsoft’s official website or an authorized reseller. The package typically includes a product key necessary for Office activation after installation.

Once you have the product key, proceed with downloading Office 2021 Professional Plus:

1. Sign in to your Microsoft account or create a new one.
2. Enter the 25-character product key.
3. Select language and architecture (32-bit or 64-bit version).
4. Click “Download”.

While ODT deployment instructions are well-documented, this option is excessive for regular users — the standard online installer suffices.

Installing Office 2021 Professional Plus

After downloading the Office 2021 installation package, run the downloaded file and follow the installation wizard prompts:

1. Double-click the installation file and confirm execution.
2. Accept the license agreement.
3. Specify the installation path or keep the default option.
4. Wait for installation completion.
5. Enter the product key when prompted.

If errors occur or installation stalls at any point, check the event log to determine the cause, restart your computer, and try again. Contact Microsoft support for assistance if needed.

After installation, Office 2021 activates automatically with a valid license and internet connection. To verify:

1. Open any Office application, such as Word.
2. Navigate to “Account” or “Help”.
3. Check the product activation status.

Proper activation will show “Product Activated” and the installed Office package version, such as Microsoft Office Professional Plus 2021.

Getting Started

After activation, you can immediately begin using the applications. At first launch, the system will prompt you to sign in to your Microsoft account for settings synchronization and cloud service access, but this step can be skipped.

By following these step-by-step instructions, anyone can easily download, install, and begin using Office 2021 on their computer. Happy installing!
