Why do I see the error message "The specified folder has R20XXx update X installed" when installing a MathWorks Product?

Install Error:The specified folder has R20XXx Update X installed.To add products to this installation, see this MATLAB Answer.

This error will occur when trying to install products into an existing installation folder that contains a different Update level. The resolution is to install online using the MATLAB Installer by selecting the "Log in with a MathWorks Account" option to download your remaining product installation files. This will install all products to the same Update level. 

If the online installation workflow cannot be used you will need to uninstall the installation of MATLAB, and reinstall. After reinstalling MATLAB, then apply the Update with either the online or offline workflow.

Which makes it absurdly painful to install just some toolboxes. How about allowing the Installer App to ignore update levels until after the user has selected products to install?

Yes, this is really user UN-friendly. I use the setup_legacy.exe command with two installer_input files to install base Matlab from one subscription (University TAH package) followed by adding other features held only by our department from our separate "child license" subscription.

Today I worked out that I can still do the TAH part with "mode=automated" by calling bin\win64\setup_legacy.exe -inputFile NNN

However, the next step in my BAT script tries to do the second stage, adding features to the existing directory with R2020a base Matlab, but that step halted with this error message about update levels.

Both runs of setup_legacy.exe were from the exact same "download without installing" of R2020a update 1, retrieved yesterday 2020-04-28. They both ran from within the same setup directory heirarchy, so they ought to reflect the exact same update level.

This is a bummer.

I can confirm that from a "download but do not install" R2020a setup directory in D:R2020a_setup\, one can do:

admin command prompt:

D:

cd D:\R2020a_setup

bin\win64\setup_legacy.exe -inputFile my_installer_input.txt

This installer input can contain the old directives

mode=automated

automatedModeTimeout=1250

I have these right after "AgreeToLicense=yes" and they are working as in past releases.

Note that to run a second silent install from the command line to add features to a base install of R2020a, you will need to:

a) do the base install

b) launch R2020a, do Help->Check for updates and apply the R2020a update 1

With the update applied, 'ver' will return text that includes

MATLAB Version: 9.8.0.1359463 (R2020a) Update 1

c) exit Matlab, then proceed with further command line silent installs to add features from another key, such as a child license on top of the base install from a university TAH subscription.

If you don't stop and do (b) prior to c), the silent (automated) install will fail with a warning that the update number does not match.

Note, I found that you need to download the latest install package from the web. Using the one from the orginal installation, which is how I started, is the cause of the problem. The answer is not clear on this and "Log in with a MathWorks Account" is confusing. If you run into the above error, I'm guessing the proceedure would be to 1) update matlab to the latest update from within Matlab, 2) download the installation software from the Mathworks so that everything is running the same update, 3) run the install package.
