Either (a) download the self-installing exe from sourceforge and run it ( see http://gretl.sourceforge.net/gretl_data.html ) or (b) open the gretl datafiles window (the right-most icon on the toolbar), click the "Look on server" button, select a package and click the install icon or right-click for an Install menu item. I just checked both of these methods on Windows 7 and they worked fine (I installed the Wooldridge data from the exe file, and the Verbeek package by selection from the server window in gretl). Note that at one point the Install icon for datafile packages on the server was not working reliably, though using the right-click menu was OK. But the icon-click problem is not present in the current gretl release (1.9.7). Allin Cottrell
