I have Matlab 2016a installed. I have currently two licenses associated with the currently installed Matlab. I want to deactivate the outdated license. When I do it in the License -> Deactivate Software ..., it asks me to Change the Write Protection on Your Drive and Try Again. I don't know what write protection here means. Can anyone help?

It's wanting to change a file where it's not allowed to write to. It could be that it's in the Program File folder or somewhere. Try running your browser as administrator. If that doesn't work call the Mathworks for the fastest, and free, help because we can't do a whole lot with license/activation issues since we don't work for the Mathworks.

If you are using MS Windows, right-click on the MATLAB icon and tell it to Run As Administrator

I know that the question raised in the past, but let me share my measure; if you are on Windows, you can launch matlab as administrator. Then, you're supposed to deactivate your account even though you're locked out of the disk access. Hope that this will help someone in the future. Thanks.

I had this problem and was able to give the user full control of c:\Program Files\Matlab
