thanks for the quick reply.
Your link helped me solve my problem, there i found the administrator links page, where i could find the files that i needed in the first place to do the silent install.
When driver files for admins available, you probably could place a link to them in the main driver download page.
I knew i had the wrong files in the first place but i couldnt find a link to the correct (zip) files.
Thanks for your help
