application program not working on another computer

[thib101200]

Good morning all, I made a program which allows to read and record in a table the values of a balance connected to a computer. All this is in a state machine to be able to backtrack if necessary. the program works very well on my computer, when I transform it into an application on my computer it still works very well but once I change computer the application is very slow and especially the value of the balance cannot be displayed . I could not get the information from the balance but everything else works. What can this be? Thanks, have a good day

Did you make an installer for your program so that all the proper dependencies could be included when you put it onto another computer?

I start in labview. I have only been using labview for -month. i don't know at all how we can see and know her?

All LabVIEW applications need the LabVIEW Runtime Engine to be ran on another computer. This is about 200MB I believe, just so you know. Other things may be required depending on your application. Build an installer for your application like this:

even with the setup program create and install on the other computer the display of the balance still does not work

Hi thib,

you were recommended to create an installer with ALL needed drivers.

Did you install ALL of them?

How is the balance connected to the PC?

Does it require a serial port, and does your software use VISA functions?

Did you select the correct COM port in your software?

Did you note any error messages in the software? When you don't receive data you should get error messages instead!

[thib101200]

yes I created it with all the necessary drivers the scale is connected by a USB cable yes a serial port is necessary and yes my software uses the visa function the selection of the com port is automatic no I have not noted an error message in the software but I have an error input and output

When you plug your USB device into the new computer, check Windows Device Manager to make sure the COM port is what you expect.  

You can also use the Device Manager to change the device to use a different COM port.  

[thib101200]

in the device manager window I am told that the com port is working normally and yet it still doesn't work

If you cannot read the scale you should get an error out from the VISA Read node, probably a timeout. Add an error indicator to your Front Panel to view it.

Would you mind uploading your code for us to check?
