When downloading Matlab r2020a I get an error and it doesn't want to continue. The installer has created a zip, unpacked but upon set up I get an error message 'Error communicating with the backend services'. System requirements are good. Windows 7, service pack 1, Intel 64 bit operating, 4.0 G RAM and sufficient discspace avaiable ~50 GB. I'm having this error for the last two days. How can I avoid this error and download the Mathlab Simulink R2020A product?

Had the same problem, but on a second PC the installer started just fine (within the same network). It has something to do with blocking the communication to the MATLAB servers, so first check any antivirus/firewall software and temporarily disable it. For me this didn't solve the problem, but I got it running by executing the "setup_legacy.exe" in the "_temp_matlab_R2020a_win64\bin\win64" folder which got unzipped from the downloaded installer. Hope you get it running to. Stay save! (PS: I am not aware of differences of the legacy installer from the normal one, so please check you get the resulted setup you want!)
