Thank you for your purchase! We're delighted that you've chosen our Office package. If you've just received your Office 2021 and aren't sure how to get started – no problem. This guide will walk you through the complete installation step by step and ensure everything runs smoothly.
Before you begin, you need the right version for your system:
64-Bit Version: https://rb.gy/mxbp4u Ideal for modern and powerful computer systems with appropriate hardware
32-Bit Version: https://rb.gy/lsh55o The most reliable choice for maximum compatibility and stability
Our recommendation: Use the 32-bit version as it works most reliably with most systems and add-ins. This saves you potential compatibility issues.
Before you install Office 2021, you must completely remove all old Office versions. This is the most common reason for installation problems and errors. Here's how:
Go to Settings → Apps & Features
Or use Control Panel → Programs and Features
Search for all Office entries (2019, 2016, Office 365, etc.)
Uninstall each version individually
Very important: After each uninstallation, you must restart your PC. Otherwise, remnants will remain that could block the new installation.
For a truly thorough removal, we recommend the free tool Revo Uninstaller:
Download Revo Uninstaller for free and launch the program: https://www.revouninstaller.com/de/
Search for entries such as: Microsoft Office 2019 Click-to-Run or individual programs like Word, Excel, Outlook
Uninstall each entry individually
Then select the "Advanced" scan mode
Delete all found registry entries and temporary files
Repeat this for all Office components
Finally: Restart your PC. Your system is now clean and ready for the new Office 2021 installation.
Now it gets simple and straightforward:
Download your Office package using the download link listed above
Open the file by double-clicking – Windows 10/11 will automatically mount it
Start the installation via start.bat or run
Important: Do not use programs like WinRAR or WinZip – this can damage the folder structure and cause errors.
If necessary: Right-click on the installation file → "Run as Administrator" – this often fixes permission issues.
After successful installation, you need to activate Office to use all features:
Open Word (or another Office program)
Click on File
Go to Account
Select "Enter product key" or "Change license"
Enter your Product Key
Done! Your Office 2021 is now fully activated and ready to use.
Problem: Installation fails or is interrupted?
Solution: 99% of problems occur because old Office versions weren't completely removed. So definitely take the time for preparation – this will save you stress and frustration later.
Problem: After installation, the programs won't open?
Solution: Restart your computer and try again. Often a restart in safe mode also helps.
With this Office 2021 installation guide, everything should work without any problems. The most important thing is to completely remove the old versions – that's the key to success. Enjoy your Office 2021!
