Hi,  
I´m trying to use the Module: OpenIGTLink to get matrices from Matlab into 3D Slicer(4.8.1). Now I have downloaded therefore the Slicer Extensions and the zip folder for windows (64-bit). When I want to drag and drop the TrackerServer into the cmd window nothing happens. It is not taken in. (by the way if it´s important: When I just try to open TrackerServer itself, in a millisecond a window appears and closes again)  
Can anyone give me recommendations how to solve this problem? It is really important for me and I can use any help.  
Thank you very much!

You should set the parameters (i.e., server IP and port) to the TrackerServer!

In the cmd console, you Can input the command “path/TrackerServer localhost 18947 20”
