There is a bug within MATLAB R2015b that affects the MATLAB Add-ons Explorer and Manager. When either the network license manager or WLAN System Toolbox are installed in the same location as MATLAB it causes the Add-ons Explorer and Manager to load indefinitely.
In order to resolve this issue you can install the patch from:
or perform one of the two steps below:
- Uninstall the network license manager or WLAN System toolbox off the computer running MATLAB and install it on a different computer.
Or, if the network license manager must be on the same machine.
- Uninstall Network License Manager and install to a new location (that is not MATLABROOT).
This is fixed as of R2016a.
