Hi Gert,
This problem does not happen under normal working conditions, and cannot be reproduced on any of our working and testing Windows machines, including Windows 10, 8.1 and 7 SP1.
This problem is being caused by ucrtbase.dll (Universal C Runtime), which is a system component. The error code 0x40000015 means STATUS_FATAL_APP_EXIT. You may have a wrong or damaged system configuration. As John says, rebooting may help sometimes. My recommendation is doing a complete system reinstall to start with a clean Windows instance, preferably Windows 10 if possible.
