Please post the message as text. It is horrible to read the screenshot with scrolling in different directions.
Please be careful with the personal details you publish in the net:
I've replaced the image by a more readable version and removed the personal data.

The error message tells all known details already. COM4 is not available. Other ports are not availaible also. Matlab suggests to use instrfind. So did you try this already?
