It could be as simple as your friend Checking-in to His Profile > Select Product (757-200 Base Pack in this case) > Extended Download Service > Get New Links and download a new installer to see if that fixes this problem.

It could even be worth doing a complete uninstall and remove the registry entry for the 757 as per KB #685, then doing a reinstall. He can always try this one before moving on to a downloading a new installation file.
