Error in launching "Metronome(X)": Actor (Internal Use).lvclass:Launch inside Dynamic Launch Shell.vi

[James Powell]

Start Metronome throws error 40284, Error in launching "Metronome(X)": Actor (Internal Use).lvclass:Launch inside Dynamic Launch Shell.vi

Preliminary:: Seems to occur if TCP actors loaded. Doesn’t occur if Metronome in project by itself. Also seems to not happen if TCP actor launched first.

[James Powell]

Actually, doesn’t seem to be just TCP stuff. May be Actor type2 involved. Investigate.

[James Powell]

A self-started ActorNR cannot launch Metronome when it is in the main Messenger Library Project, but can if it is in a separate project (so some other thing loaded is causing problem).

[James Powell]

Metronome doesn’t start if project has:

ActorNR that calls Metronome (or possibly any Internal Actor)

TCP Listener Actor (or possibly any other internal actor?)

‌

[James Powell]

Actually, just the TCP Listener does it. This calls the TCP Connection, so maybe that is involved.

[James Powell]

Swapping out the Actor.lvlib constant to an Actor Internal, in the startup info of the TCP Listener, fixes the problem:

Theoretically, TCP Listener could have been given an Actor type2 to launch to handle connections, so perhaps this is where the LabVIEW issue is.

Resolving, but it would be better to find a different solution eventually.
