Hello rattofest,
I think I might have found the issue. When you download an executable to a Fieldpoint target, the front panel of the program is removed to save space. Therefore, in order to be able to connect to a remotely running executable, a copy of the executable must remain on the host in a specific location. Before copying the executable to the controller, place a copy of it on your host PC in the following directory:
C:\ni-rt\startup.exeEvery time you change and rebuild the executable you will need to copy it into this directory on your host PC before downloading it onto the RT target. Let me know if this solves the issue.
