Concerning the FRC forlder for examples, i'm unable to download or access the folder for 64 bit Labview 2020. As i'm planning on using the example 'simple digital input' as a basis for programming a limit switch for a stepper motor system. This is based of referencing 'Programing a limit switch?' in NI forums.
Regarding your question: the FRC software does not execute in LabVIEW 64-bit (hence why the FRC software downloads always install the 32-bit version), because of the LabVIEW Real-Time module used to deploy to the roboRIO.
