Hello,
I opened your code and it looks like the configuration VI you're talking about is the TSI4000SerialReadingConfiguration.vi. I don't see any reason that this would cause problems during the exe build process, nor problems when run as an executable, unless you were running it on a machine which didn't have the VISA runtime engine installed. In any event, I noticed that you are using sequence structures to dictate dataflow in many places, and this doesn't always compile as efficiently as dataflow code would. Generally speaking there are few cases where a multiple-frame sequence structure is necessary. I have attached a different version of your VI which illustrates a different way to program the functionality of that config VI. If you suspect that this is a problem with using the VISA VIs, try building a simple vi for your serial port which you can use to do a loopback test (just open, write, read, and close on the same port, and be sure to connect pins 2 adn 3 on your db 9 connector), and you should see the problem is not with that part of your code. If you're having trouble debugging your exe, perhaps you can put some indicators in your code at places you suspect there's a problem, and determine exactly where things break down. Feel free to use the VI I have attached here in place of your config VI - it should be functionally the same (although arguably cleaner), so I'll be surprised if it solves the problem.
We need to get to the heart of this problem, confirm exactly what VI causes the error, where in that VI the error occurs, when it occurs (first time it's called, second?), and what the exact error that is generated is.
I hope this helps!
Best Regards,
JLS
