When you set the SkipNoExecutionFileMessage registry entry to TRUE, and you open an NX DCI measurement routine with an available NX session, the "Couldn't find the NX execution file!" message is not displayed.
If you set this entry to FALSE, then that message is displayed.
This registry entry is located in the NX section of the Settings Editor.
