Error message: Failed to open...

Question:

When you start the VirtualBox programming station, the following error message appears: Failed to open a session for the virtual machine TNC640.

Answer:

Windows 10 Build 1709 (Fall Creators Update) has the problem that the programming station won't start. Version 5.0.40 of the VirtualBox, which HEIDENHAIN supplies together with the programming station, does not run on this version of Windows.

Download and install version 5.1.30 of the VirtualBox. Then the programming station will also run on Windows 10 Build 1709 without any problems.

Link to version 5.1.30:
