Hoya!
@Jose
Just check the installer with a text editor. Check for the line which gives the uncorrect argument. It happens sometimes, the installer want to use a certain path but yours got a slightly different name, hence the error.
Hope this helps.
Alternatively, go to
www.whdload.de and download the latest update.
Or find a pre-installed pack as leirbag28 said.
