The following installation guide applies to the following versions: Microsoft Office 2021 Pro Plus Retail unbound
For a detailed guide with screenshots, visit our step-by-step tutorial.
1. Uninstall old versions of Office:
Before you install the new Office package, all old versions of Office must be uninstalled from your computer. You can find and uninstall them in the Control Panel > Uninstall programs > programs. Sometimes this is not enough for the new Office to activate properly. Detailed instructions on how to uninstall from your computer using "get help" of all other versions of Office can be found here.
Note: This is also required if Windows has just been installed and Microsoft 365 has not been used before. Because every Windows installation already includes pre-install files from Microsoft 365.
2. Download the Office package:
Follow the link in the invoice to our download center and download the Office package. In the download center, on the left, select your desired installation language.
3. Installation:
Double-click the downloaded ISO file to embed it into your system. You will now see a virtual DVD drive in My Computer. The installation of the software is started by double-clicking on "Start" and not on setup.
4. Enter product key and activation:
After the installation is complete and verified, you can enter the product key. To do this, open Word and click on "File" in the top left. Select the sub-item "Account". Pretty much in the middle at the top, you will find "Change Product Key". Enter the key here and complete the activation. Close the Word. Open the Word again and when prompted to activate the product via the Internet, simply follow the steps. Restart the computer if prompted.
If you have any further problems with the installation or activation, please write to us. Simply use our contact form and send a screenshot of the error message at the same time. We will be happy to help you.
