MATLAB R2020a update_installer.exe offline update doesn't working

https://www.mathworks.com/downloads/web_downloads/show_updates?release=R2020a

R2020a Update 1 Package was just released in that link on 22 April 2020.

After you click download it will open this link

https://www.mathworks.com/downloads/web_downloads/download_update_installers/R2020a%20Update%201

Offline installs are supported via a non-interactive command line-based installation process.

1. Install R2020a if you have not done so already.
2. Read the R2020a Updates Install Instructions.
3. When you are ready to apply the update, download the appropriate Update Package file below.

Now the problem is that, the second step says Read the R2020a Updates Install Instructions.

https://www.mathworks.com/help/releases/R2020a/install/ug/update-mathworks-software-on-offline-machine.html

But by opening that link, this note appears

Note
Use this procedure only for R2018b and later.

It's a useless instruction.

If you try to run the command on windows cmd, for example like this

C:\Program Files\MATLAB\R2020a\bin\win64>update_installer.exe -updatepackage C:\R2020a_Update_1_Windows_package

You'll get this error on %TEMP%\mathworks_yourusername.log

So where is the R2020a offline update instruction?

I could confirm that I could offline update R2019b into update 5

How do you update R2020a offline as usual just like R2019b before?

[James Richard]

any news?

[Star Strider]

I had similar problems with R2020a Update 1.

I ‘solved’ it by continuing to try the update. On one computer (two-year-old desktop) it worked on the second attempt, on the other (relatively new laptop) I finally got it to install on the tenth attempt.

These obviously involved quitting and re-starting MATLAB each time. It is necessary to wait about ten minutes after shutting down MATLAB to attempt the update, since the update will fail unless MATLAB is completely off as san active process. Sometimes that seems to take a while, even on fast computers.

I have no idea what the problem is with the updates. Sometimes they work without problems, and other times ...

Answer 1

[Walter Roberson]

So where is the R2020a offline update instruction?

They are at https://www.mathworks.com/help/releases/R2020a/install/ug/update-mathworks-software-on-offline-machine.html

Note
Use this procedure only for R2018b and later.

You are installing R2020a and R2020a is later than R2018b, so there is no reason not to use the instructions.

A lot of people look at current documentation and assume that it applies to older releases as well. Mathworks is explicitly pointing out to people that the current procedure does not apply for R2018a or earlier.

[James Richard]

I tought it was the word "later" as "happening towards the end of a period of time". I mean, R2018b and the older version will get no support in the future right? Why not use the words "R2018 and newer" instead?

Whatever, it doesn't matter right now. The problem of R2020a offline update not working is still exist.

Any solution?

[Walter Roberson]

"or later" refers to releases that were created after the noted period of time.

[James Richard]

Ah alright I admit my mistake. Just how do I offline update R2020a without getting error like that?
