When will Add-On Explorer will be unavailable again? The problem remains for more than 2 months. Is there an alternative solution? Our work falls behind because of that.

Try running Matlab with administrative privileges. That is, in Windows right click on the Matlab icon and select the 'Run as administrator' option from the menu. Try opening the Add-on Explorer now and if you have a valid License, then you'll find it working. :)

This is my experience and its working for me with R2106B and Win10. I will give you an example with case of installing OS Generic Video Interface to enable Matlab 2016B accessing webcam.
1. Download Support Package via browser here (or maybe another link) Click on Get Support Package. Save the "osgenericvideointerface.mlpkginstall" in any folder you prefer.
2. Start Matlab R2016B and select the prefered folder where "osgenericvideointerface.mlpkginstall" saved.
3. In the Current Folder of Matlab interface, rightclick on "osgenericvideointerface.mlpkginstall", choose download and install.
4. Follow the installation procsess.
5. Check with "imaqhwinfo", in the InstalledAdapter there should be "winvideo" there.
I think for other case, it will also work. I tried with package for OS Generic and Kinect. If you need another package, just search the "*.mlpkginstall" file and follow the step above. Good Luck

According to Mathworks Support,
in case MATLAB is not using a valid license number, that results in Add-Ons Explorer to not function appropriately.

Student Suite can be purchased through the Mathworks web site. Sometimes universities make licenses available to students.

I was having a problem with this on my Mac running R2018b. I was able to get to the 'Add-On Explorer' by:
1. Clicking the 'Add-Ons' drop down in Matlab.
2. Then clicking on 'Manage Add-Ons.'
3. Within the 'Add-On Manager' window, in the upper right hand of the window is 'Get Add-Ons.' Click on this.
This brought up the 'Add-On Explorer' without a problem.
I hope this helps.

Please try to run the following in the MATLAB Command Window:
>> opengl software
And then try opening the Add on explorer again. It worked for me.
If that works, you can save the preference so that MATLAB always opens with Software OpenGL by running:
>> opengl('save','software')
