TCP Read doesn't work sometimes

[Moogie]

Hi Everyone, I have a problem where my build .exe doesn't work on some computers but works fine on others. it uses a tcp connection to grab data off a custom server program which packages bluetooth data. The program build works fine on my development computer as well as another desktop, but on a 3rd computer the code simply doesn't read the data from the server. I've disabled windows firewall but i have no idea what else to try - anyone have this problem before?

It's not always just Windows Firewall.  Is this a company computer?  I've had similar situations and it all came down to IS being weird with their security.  I'd go talk with them.

Thanks for the response, I figured out the issue. apparently i needed to build an installer to get the executable to work. It worked fine by its self on our developers computers but on a computer with only the runtime engine installed it did not. presumably the installer fills in the missing functions. i've also noticed that some property nodes work correctly in development, but not in the executable. after the installer was run those nodes now function correctly. interesting lesson learned.

That tells me there was a driver you did not install on the other computer.  LabVIEW 2013 tries to automatically figure out what drivers you need when you configure an installer.  This issue does not sound like it had anything to do with the TCP/IP.
