I am trying to install Simulink support packages via targetinstaller. My PC is using a proxy to connect to the internet.

When I start targetinstaller (via the command line or Add-Ons > Get Hardware support packages in the toolstrip), I can select the support packages I am looking to install. However, when I proceed to log in to my MathWorks account, I receive the following error:

ERROR: "An Error has occurred"

My password and account name are correct. I can access the web using the WEB function. I can access online documentation - the requested login for the online help works fine.

I get the same error message whether or not I configure MATLAB to use a proxy server.

I tried downloading the support packages directly from MATLAB central. However, on installing, the same login was required which returned the same error.
