R2022B Update4 is not offered

Is it just me or the update 4 is not offered via the menu Help => Check for Updates

I'm using Update 3

[Les Beckham]

It is not just you. There is definitely something weird going on with the phantom update 4. Perhaps they found a bug and retracted the update until they fix it.

[Walter Roberson]

Mathworks has indicated that the offline installer has a problem, so the update is not fully available.

[James]

Pretty sure it's not just the offline/manual installation of the Update since I was able to manually push for the update using update_installer.exe and it failed on one of my computers. Once I restarted my computer and ran the executable again, it worked.

Procedures for installing on Linux, please.

Answer 1

[Bruno Luong]

The online update for R2022b Update 4 is NOT offered by TMW.

Workaround : do the offline installation.

Risk: you need to uninstall your current MATLAB version, if any. So be aware if this procedure goes wrong.

Go the TMW and dowload the installer, make sure the version is R2022b Update 4

Launch the installer, enter your license information (User, password, lenceses number)

When you arrive at Destination step, click on Advances Options drop down box and select Download Without Intalling

Then click Next. When it finishes, go to the download destination folder navigate inside MathWorks\R2022b\2023_* until you see the file setup.exe. Double click and follow the installation procedure.

After the installation ends, launch MATLAB and check the right version and test if it runs fine

If it's OK you can cleanup by deleting the installer files (matlab_R2022b_win64.exe on Windows) and the folder MathWorks in Destination folder and perhaps some _tmp folders left out by the installer.

This seems extreme.

I’ll wait for R2023a!

[Rik]

Since I guesstimate R2023 will be available in about 2 weeks, I can only second that advice.

[Walter Roberson]

Closer to a month. The "a" releases are released very close to the beginning of spring.

Answer 2

[Star Strider]

Try this —

Get R2022b Update 4

That’s where I had to go to get it.

.

[Bruno Luong]

I don't want to uninstall my current MATLAB, especially Walter warns could break installation

[Star Strider]

I just checked. Although I downloaded it and thought I’d installed it (I didn’t check afterwards), both installations (desktop and laptop) show Update 3, and checking it just now says that MATLAB is up to date (with Update 3, not Update 4).

I have no idea what’s going on with Update 4. My maintenance is up to date, and I already paid for R2023a/b when I got billed for it in December 2022. I never got any notice (gold bell and red dot), either.

R2023a should be out in another month or so, so perhaps Update 4 is simply not important.

[Bruno Luong]

Update 4 supposingly corrects some ugly bugs with non-square complex linear systems on both CPU and PU reported here.

"The offline update package for R2022b Update 4 is disabled for download to avoid a known issue."

This applies only to the offline updater.

[Bruno Luong]

@Walter Roberson I'm confused: what exactly is "offline updater"? Is there any official anouncement by TMW?

Checking the bell or menu "Help> Check for Updates " are online or offline? (To me they are online since it needs a proper internet connexion.)

[Walter Roberson]

offline installer is for the situation where you do not have an internet connection. I am not certain at the moment whether it is the same installer that is used when you are installing without a GUI (such as to a Linux server)

[Bruno Luong]

IIUC "offline" is not applicable to my original question. I have proper internet connexion, up to date maintenance license.

[Walter Roberson]

Right. It is available selectively but not through all paths, because of the problem.

[Star Strider]

This works (as I discovered earlier today in another thread) —

In Windows 11 File Explorer, drill down and then click on:

C:\Program Files\MATLAB\R2022b\bin\win64\update_installer.exe

(or copy that and run it from the Command Prompt) and everything works perfectly. Nothing else needs to be done. (MATLAB R2022b Update 5 is current.)

[Bruno Luong]

Yes, the update_installer.exe is good trick.

Here is the official offline update instruction

IFAIK if user omits the option -updatepackage package_folder it will download the latest update from the internet, instead of installing the predownloaded package.

Answer 3

[Steven Lord]

Please see the accepted answer on this Answers post.

[Star Strider]

I just clicked on that, chose ‘Get Updates’ in the dropdown menu, clicked on ‘R2022b Update 4’ and ... crickets.

It seems to be a dead link.

[Bruno Luong]

So it seems that the opposite of Walter information and this accepted post occus:

• offline: working (download the installer, download UPDATE 4, then install)
• online broken -No bell, no getting from Check for Updates from MATLAB GUI)

I'm I misundertand something or all those posts are really confusing, if not wrong?

[Star Strider]

Thjs short answer seems to be that ‘R2022b Update 4’ is not available for download and may not be, before the release of R2023a.

[Bruno Luong]

This is not true. If users download the installer now, one get the R2022B Update 4.

[Star Strider]

It doesn’t work when I try it (using the above link). It’s still a dead link.

How did you manage it?

Answer 4

[Cris LaPierre]

I don't know if this will be helpful, but I was just notified through MATLAB today about Update 5. I was able to install it using the Bell notification.

Reference: Updating an Existing Installation

[Star Strider]

That helps with respect to knowing what to look for.

[James]

This isn’t going to show up for everybody right now, though.

[Bruno Luong]

I guess if you are using Update3 all successive updates will not showed up.

As discussed elsewhere the best way is to run (if you are under WIndows)

C:\Program Files\MATLAB\R2022b\bin\win64\update_installer.exe

[James]

The update_installer is also not a Windows exclusive. It appears on Linux and Mac as update_installer.sh.
