The following installation guide applies to the following versions: Microsoft Office 2021 Home & Business bound

Quicksteps

1. Before installing the new Office package, it is necessary to uninstall all old Office versions from your computer. You can find and uninstall these in the settings under Apps. If necessary, download the Microsoft SARA-Tool for simple bug fixes to make sure that all old Office versions are completely uninstalled. Microsoft gives a detailed guide on how to uninstall all old Office versions.

Hint: This is also necessary if the Windows is a fresh installation, and you never used Microsoft 365.

2. Follow the link from the invoice to our Download Center and download the Office package.

Hint: We always recommend downloading and installing the 64-bit application. If you prefer the 32-bit version, you can select it in our Download Center.

3. After that, you can start the file with a double click. Windows 10 and 11 should do this automatically with Windows Explorer by double-clicking on the file.

Hint: If this does not open, you can download and install a free virtual disk management and creation program. Virtual Clone Drive is recommended here. You can download it here. Do not extract the files with a program like WinZip, WinRAR or similar. It will damage the file system.

4. After the Office file has been integrated from our download center with a double click, start the installation by double-clicking on the file "setup". If necessary, you must start the file by right-clicking on it and with "Run as administrator".
5. After the installation has been completed and you have verified it, you can enter the key. To do this, open Word and click on "File" in the upper left corner. Here you will find the sub-item "Account". There you will find on the right side of the now opened menu "Enter product key" or "Change license". Enter the key here.
