rs-232 not working when compiling to EXE

[AOrtin]

My application uses rs-232 ports and works fine when run from the LV development system. However when I built it using the application builder and run the EXE file it does not. No error messages are generated by my program justs stops and I have to close it using the task manager. Hhat must I do in order to be able to run the EXE and use the serial ports as from the development system?

Does your executable run OK when run on the same computer as the LabVIEW development system?  If you are running the executable on a different computer you may need to install NI-VISA, or create an installer and check the "Serial Port Support" box.

I've seen this problem when you have controls specifying channels in your "original" VI.  I would try changing the control(s) to constants.

I have exactly the same problem. Running my vi under the LV environment, I can access the instrument with rs232, but when I will use the exe files on a second computer I can't even choose the serial port name nor will it work with a constant. So I tried to install labview on this computer and now it is working.
But this is not the solution as I would like to use the exe file on different computer for lifetime measurements and I will not install on every computer labview. Is there a possibility to solve this problem?

And did you include the VISA run-time when you installed the exe? This is an option when you create the installer - Installer Settings>Create Installer>Advanced>Serail Port Support.

My last exe caused me a great deal of angst also.  Mine didn't involve RS232, so please excuse me if I am getting off the subject.

I transferred the MAX settings from my first computer to the second, according to NI's instructions. That didn't work so I configured MAX on the second by hand.  I made sure that my channels were named exactly the same as the first computer.  This solved my problem.

Good Luck
