in the 64bits system MATLAB 64-bit software does not have the LED control ActiveX control, the LED ActiveX control controls are located in the Gauges Blockset module, and gauges Bloc Kset module can only be installed in the version of Matlab 32-bit (not necessarily need to install in window 32-bit, I test environment is win10 64bit), in WIN10 64-bit environment installed by default is Matlab 64-bit, So the gauges Blockset module will not be installed, of course there will be no ActiveX Controls!
The workaround is to install the 32bit version of Matlab in a WIN10 64-bit environment.
first of all, I installed 32bit matlab 2014a under the Win10 64-bit system, and the control list contains Gauges Blockset module, but the LED ActiveX control was not found in use, and then the MA Tlab 2014a uninstalled, installed 32bit matlab 2012a, you can use the LED ActiveX control. later thinking may be due to the previous 32bit matlab 2014a crack is not complete, only led ActiveX control controls are not available.
