This solution is NOT officially tested but MAY work.

Does the pen(s) work with USB-C?

USB-C is a physical specification compatible with the earlier protocols used by the various C-PEN models.
A USB-C to USB-A adapter is however required.

Unexpected error

If C-Pen software crashes due to “Unexpected error” or “Object reference not set to an instance of an object” it most likely depend on lack of/wrong versions of one or more of the three 3 Windows dependencies the software rely on. These three dependencies are C++ Redistributables 2005, 2008, and 2010.

To resolve the problem, it´s recommended to manually download and install all three.
