lexmark printer driver - installation problem

[Yawa]

I can add the drivers to OemPnPDriversPath and it installs correctly, but after this, a setup starts, because in the language folder is a setup.exe

I checked the ini files, but there is no line that says "start setup.exe in the language folder". Only the language path is there.

I think the unattended install for this setup would work with the switch -s, but where i have to add it?
