Silent installation of free PDFCreator

I have been trying to install PDFCreator-4_4_1-Setup.exe silently with absolutely no user interaction.

I have used the following command: GmbH>PDFCreator-4_4_1-Setup.exe /ForceInstall /VerySilent /LANG=fr /COMPONENTS="none" /NORESTART /NOWELCOME.

No matter the params, the installation doesn't start silently: I see the installation Welcome screen everytime.

How can I remove that "snag screen"? Thanks
