Serial wont work in another computer

[Evps]

Hi,

I created a software to communicate with a CLP with Serial RS232, and it works perfectly fine on my computer. I created a .exe version of it to run on another computer but it just wont communicate.

I already checked baud rate and everything. On my computer it works perfectly fine. I guess there is something missing on the other computer, some Visa or Runtime, I already installed Visa serial 3.8, run time engine and some other things, but I just does not work.

Does anyone have had the same problem and solved it somehow? Maybe I'm building it wrong, but I looked for tutorials and it seems right.

I use LabVIEW 2011 and want my software to run in Windows 7.

Thanks

LabVIEW Run-time Engine?

I instaled Labview runtime engine 2011, NI Visa runtime 3.8, NI system configuration runtime 5.0.0 but nothing worked

Do you have a real RS232 port or are you using some sort of USB-RS232 converter device?

Your build is immaterial. An exe does not include hardware drivers and this has been discussed numerois times. Did you create an installer? There, you have the options to include LabVIEW runtime and NI-VISA runtime. A VISA serial 3.8 makes no sense unless you really are talking about NI-Serial and are actually using an NI USB-RS232 converter. The latest version of VISA is 5.2.

I'm using a USB-serial rs232 converter, I have no real ports (nor in my computer or the other one), but it works fine on my computer.

I didn't created an installer, I thought that if I crated an .exe and installed separately the Visa it would work. I will try it!

And is it in fact an NI converter? There is no such thing as NI VISA 3.8. And if you do not have an NI product, you have to install the driver that came from the vendor.

Not VISA 3.8, sorry, i meant serial 3.8 (that you already told made no sense to install).

I'm not using a  NI converter, i'm using the driver from the vendor properly ( i tested it on simple term gold and it works fine on the other computer and on mine).
