Issue Details

We encountered a problem launching the "Real Time Application" executable of our cRIO project for the first time. Here is the error message: LabVIEW Generic File I / O Error the File could not be loaded.
How to fix this problem?


If you use non-standard ascii characters in the element names that will be deployed (like VIs, ctls, shared variables ...) in LabVIEW, then your RTEXE will fail to work. You should rename these elements (modify "é" and "è" to "e" for example), and reload them in your project explorer window as well as the RT Main VI.
