Executable Problem

[Tachyon]

      I built an execuatable out of one of my vi's a few days ago which works fine on all the computers I have put it on except for the one that I actually need it to work on (thank you, Murphy's law). The exe is supposed to read something from one of the computer's COM ports, specifically either COM1 or COM3. When I built the exe, I defaulted it to read from COM3. When I try this exe on most computers, it recognizes COM3, as well as all of the other COM ports on the computer and runs fine. However, on this one computer, it seems to not be able to recognize any of the COM ports. It starts up saying it's reading from COM3, but it immedietly fails. When I try to change the COM, the only one listed is COM3 and it doesn't have the little icon next to it showing that the port is open or valid or whatever.   Any Ideas?

Naturally, questions are welcome.

You should check in MAX if NI-VISA is installed on that computer, I doubt it.

I dont think labview is installed....just the runtime engine.
I should probably start feeling stupid about now, right?

Hi !

Suppose you don't need LV.

Just install Drivers and remember to check
COM-interface's configuration in MAX.

Hi

You don't need LabVIEW, just the runtime engine and VISA drivers

If you have LV 8.x I advise you to build an installer including VISA drivers and the LabVIEW runtime.

How do I get the VISA drivers?

All of our software can be found from our drivers and updates page:

All drivers are on your drivers CDs that came with LabVIEW. The app builder should be pointing to that when you create the installer.
