Installation under Windows 7:
To install the downloaded ISO file under Windows 7, you need a program that opens the file format without burning it to a hard drive.
You can open the ISO file with a free program such as 7-Zip or WinRAR and start the installation by double-clicking on setup.exe.
You can download WinRAR here.
Installation under Windows 8 / 8.1 and Windows 10:
In contrast to Windows 7, the newer operating systems already have an integrated virtual drive, so you do not need another program to install the Office application.
To open the ISO file, please proceed as follows:
- Right-click on the downloaded ISO file and select "Open With".
- Select Open with Windows Explorer to open the ISO file.
- The opened file is now displayed so that you can start the installation by double-clicking on the setup.exe file.
