error 42 at init serial port

I built a simple application  using LabView 7.1  using serial ports and using VISA . I finish the project and built the installer. on the development PC I test the application (from the "start" menu,  and it run correctly. when I try to insall it at another PC (after  checking  that the appropirate port is valid)

I have got an error message "Error 42 occured at Init Serial Port"

what could be the reason for this problem

I am using 7.0 but have never used 7.1. But check out this setting. It may help


Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Hi there


Have you installed VISA on the target system? You can download it here:


Make sure to enable the "serial port support" option at the Advanced installer settings tab page.
