I have a non-internet connected PC. I downloaded alexnet.mlpkginstall and transferred it to my non-internet connected PC and placed it in my Current Folder. Per the manual installation instructions, I double clicked on it. MATLAB then launched the Add-On Explorer which generated the following error.
Failed to load URL. https://login.mathworks.com/embeddded-login/login.html?locale=en_US with error(-118).
I take this to mean that it attempted to access the internet and failed.
Please provide guidance ... thank you
