When installing a Support Package in MATLAB R2017a or earlier, I keep getting this message (Fatal Alert: Protocol_version). The installer says that "MATLAB is in the middle of a downloading operation".

In each case, the repair is to go into the bin directory of your MATLAB installation, and go into the architecture-specific directory there such as win64 for windows, and to change or add a java.opts file with content
-Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2

When installing a Support Package in MATLAB R2016a or earlier, I keep getting this message (Fatal Alert : Protocol_version). The installer says that "MATLAB is in the middle of a downloading operation".

The solution worked well in my 2015a version. Please be aware that, in summary, you just need to add one file to the bin>win64 folder (in the windows version) and a couple to the bugreport folder.

For my windows R2015a, I simply added java.opts to Matlab\bin\win32. It worked well.

Make sure you place the java.opts file in the following directory:
C:\Program Files\MATLAB\R2015a\bin\win64
