- 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. 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 the Microsoft 365.
- 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.
- After that, you can start the file with a double click. Windows 10 and 11 should do this automatically with the Windows Explorer by double-clicking on the file.
Hint: Do not extract the files with a program like WinZip, WinRAR or similar. It will damage the filesystem.
- After the Office file has been integrated from our download center with a double click, start the installation by double-clicking on the file "start". If necessary, you must start the file with a right click on it and with "Run as administrator".
- 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.
If there are 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 are happy to help you.
