COM Port Issue modbus

[plpablo]

Hello all 

I developed easy testing application for modbus rtu using modbus library. Works perfectly on my development laptop. Bud when I made exe and move it to target computer application do not see my com port. 

Hardware : 

1) development laptop with Windows 7 and LabVIEW 2017 

2) target computer with windows 10 and installed LabVIEW run-time 

3) usb - rs232 ftdi ft232rl based. 

I attachment screen shots and code. 

Question is why program on target machine did not find com port ? 

I checked with modpool and hardware works ok. 

Best regards
