Can't update Matlab from 2019b to 2023b under Win10

I've downloaded the 2023 update package for updating my off line Matlab system. I follow the instructions. When I start Mathworksupdateinstaller, I get a blue screen with a window schetch in the right lower corner. Nothing more. When I brake out after a while, I get told 'No permissions'. I have succesfully logged in both as admin and with my userThe cv-log contains more than 800 lines of this:

What is the issue?

I suggest that you Contact Support since I doubt that any of use here can help you with this. Include the URL of this post in your message to MathWorks so that you don’t have to repeat everything here.

First like to make sure we are on the same page there is no "updating from R2019b to R2023b". Those are seperate installations you can have in parallel. Releases may or may have Updates.

If you encounter this issue while installing an Update for 2023b - I have seen this releated to antivirus or security software (please ask you IT if they can disable it for a quick test).

Thank you for good response.

It is my error - I thought I could upgrade with the package across versions. I will then try to do a new install. However, that hsa to wait until the end of my summer holiday.

Best
