run it at a command line (I cannot read Dutch/German so not sure what it was saying) but running it at a command line then using the /? or -? will most likely get you the command line parameters. I would guess you are missing some prompt suppression or license acceptance flag. The /Quiet often works but it appears you need /passive too?
Installer: lyncentry_4417-1000_x86_de-de.exe with /quiet and /passive /log might also give you ideas of why it is not completing.
