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.

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.
