Thx. If I cancel the installation in VMWare and restart, then I see in Windows that it has been installed. But something is disturbing the process of the installation in VMWare.... I tested the Office installation with the script under a running Windows and it is installed. The two screenshots (the setup and the cmd in my Post before) are closed when the installation is finished, but at the end a window remains open (see screenshot) - might that interfere with the silent installation? No idea... Is the SourcePath = "" relevant? It's not empty in my file. There is the path where I created the file. But then the .ini comes into the Windows ISO. So I ask. Can I leave it like that or does it have to be empty?
