Touble with drivers for the Averatec AV7115-EH1

My cousin had to reformat his Averatec AV7115-EH1 and after Windows was installed he tried to install the drivers from Averatec's website. All of the drivers except for the "Cardbus" driver comes up with the error message "Please go to the Control Panel to install and configure system components." while the file is trying to be extracted from the "Winzip self extractor".

We have already looked for the Autorun.inf file but is not on there. (this supposedly causes this error messages in many other cases, but not ours.)

Thanks in advance...
