I try to install Update 1 for 2021a version offline and, as always, run
update_installer.exe -updatepackage <package_folder>
in the command line, but receive (in the log file) the message:
(Apr 28, 2021 11:30:29) Error: Specify a Windows update package.
As I suppose, Matlab updater uses Windows functions for launching update program, but something goes wrong. I have found no suggestions regarding this issue yet. Are there any ways to tackle the trouble?

Just to be sure: You have replaced "<package_folder>" by the path of the package folder?

Sure, the palacehoder <package_folder> was replaced.
I have been installing Matlab updates in such a manner about 3 years.
