Getting error message "Unrecognized function or variable 'matlab.in​ternal.add​ons.update​.GetSuppor​t PackageUpdates'" in a multiuser environment

We have a multuser machine runing Matlab.

An user reported to me this problem: When he opens matlab, he gets an error message (after many warnings) -> "Unrecognized function or variable 'matlab.internal.addons.update.GetSupport PackageUpdates'

Since I have an admnistrator account, I get no errors...

How can I solve this issue?

best regards,

Alexandre

Hi,

This is related to cache issue as MATLAB caches files on search path. Refer below links for more details.

Hi Aman,

Unfortunatelly I coundn't solve my problem....

I have ran the three commands proposed in https://www.mathworks.com/matlabcentral/answers/390813-why-s-getfileinfofortoolstrip-missing-after-update-to-r2018a

and I restarted my system....

But the problem persists...

If his code folder contains mis-named the Namespace folder, it is likely caused by Namespace issue.

My story was: I accidentaly renamed a few folder started with '@' inside a code folder that I got from a collabrotor. Once I add the entire code folder to path, when I open any .m file in that folder, the command window prompted all kinds of error similar to what your co-worker had. Once I rename those back, the issue resolved.
