Why do I receive an error: "Unexpected SOAP exception" when installing MATLAB 7.8 (R2009a) or later over the Internet on Mac OS X?

This error is triggered by the presence of an NTLM proxy which interferes with the automatic (Internet-enabled) installation of MATLAB. As a workaround, MATLAB can be installed via the manual (offline) installation method. See the Related Solution "Can I install & activate on a computer manually that cannot connect to the Internet?" for instructions on the manual installation method.
