Installing Dell Drivers: installation package could not be opened

Dell Inspiron 15 5000 Series 5559.

To get rid of the crapware I've done a clean install, but I want to install some drivers from the Dell web site. I've downloaded the files, but if I try to extract or install them I get an error, see image attached.

When I open the location they were extracted to, there are no files there!

I note in the install log that it has a personality error as below, not sure if this is relevant:

WARNING Personality Module lib FAILED to return Values via GetPersonalityInfo().

Image attached is error after attempt to extract or install drivers or applications.
