JackTrip requires that you have critical system components installed and updated
If attempting to open JackTrip shows a dialog window mentioning a missing msvcp140.dll file, it means that you are missing an essential Windows component called the "Visual C++ Runtime." You can download and install it (x64) using this direct link, or learn more about it at Microsoft's website.
If all you see is a blank window that quickly disappears, it likely means that you have an outdated version of this component. You can update it by using the same link above.
