Why do I encounter a "Received fatal alert: protocol_version" when installing a Support Package in MATLAB R2017a or earlier?

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".

[MathWorks Support Team]

This error does not occur when installing Support Packages in MATLAB R2017b.

This issue is now resolved in the following error bug report page:

<https://www.mathworks.com/support/bugreports/1741173>

Please contact MathWorks Technical Support and create a help ticket if you run into any other related issues

The attachment link in the bug report page is broken :(

[redlab]

attachment broken for me as well

Update (03/15): attachment fixed.

[Jose Corona]

The attachment link does not work!!!!

[Eduardo Edu]

The attachment link does not work!

[Walter Roberson]

Access to that attachment requires setting a cookie. You might have your browser set to reject that cookie. For example it works for me from Safari but not from Netscape, but if go into netscape preferences to Privacy and Security, and change Tracking Protection from "Always" to "Never" then I can access the attachment.

[Rajesh Gaonkar]

Even after accepting cookies, the attachment link does not open in firefox.

[Walter Roberson]

If you have privacy add-ons such as Privacy Badger then you might need to disable them.

[Tasnim Tamanna]

I'm having the same problem. Can anyone fix yet?

[Walter Roberson]

My experimentation a moment ago with Firefox showed that clicking to download the attachment failed to bring up the appropriate page whenever I have Firefox configured to tell websites "Do Not Track". Turning that off allowed me to start the agreement and do the downloads.

[Walter Roberson]

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

The .zip file you download in that link has a java.opts file (among other 2).I extracted java.opts onto my MATLAB folder and it did not work, but I moved it to /bin/win64 folder and it worked. I use MATLAB R2016a.

[Mostafa nada]

Thank you Mr Walter

That step helped me to solve my issue <3

[seifeddine hadj mohamed]

i have matlab 2015a version and i got the same problem for downloading the raspberry pi package.

i created a file named java.opts and paste the following line : -Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2

and then paste the file in the C:\Program Files\MATLAB\MATLAB Production Server\R2015a\bin\win64 path

and it worked finaly :)

Answer 7

[Efrain Teran]

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.

[Xiang Yi]

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

[febin m]

can i see the file java.opts ?

[zhengke Liu]

thank you,I follow your instruction and it works.my version is 2015b

[nanou]

can i see the file java.opts ?

To continue with support package installation:

Use "Install from Internet"

or

Use "Download from Internet" to download the complete set of files, and retry installing from folder."
