My employer has purchased the Deep Learning Toolbox for me and added it to my license. I have R2021b. I went through the installation process but when I try and access deep learning apps they are not there, and running nnstart informs me that I need the Deep Learning Toolbox.
I redownload the installer and run it and receive the message that products are already installed!

I am trying to download the newest version of matlab as I got a warning this morning when I went to open my Simulink model that I created on this same computer yesterday. I attached the warning window. But now I can't download the update because it shows me the same error as the OP. Do I have to uninstall all of Matlab and toolboxes before I update? Seems like a lot, just to get an update.

I don't know? You should be telling me the answer.
Usually, my renewal is near the end of the year in December.
Since my renewal date is always near the end of the year in December, I should not need to renew now.
I want to finish my current installation please.
