COM port not detected in exe

[sabah_TASL]

For this expression "ASRL[0-9]*::?*INSTR" also the list is empty in exe.

Just drop a VISA resource on the front panel and use its properties instead.

I had used the visa resource name, it has com ports in drop down in development vi, but in exe the drop down is empty.

Fig 3. EXE (No com ports in drop down)

Could it be that you are using the Exe on a virtual machine and the Development vi on your standard session ?

Strange that you cannot see a port in Exe when working on development, moreover COM 1 is (most of time) a RS232 port so it is always there.

[sabah_TASL]

Both exe and vi are in the same computer

What if you run the exe as administrator? 

Have you tried to change the search mode for VISA Find ?

The issue is resolved after the antivirus firewall security was disabled, now the exe is able to find the com port. Thanks all for helping me out.

It was my belief that COM ports (Serial) are exemption when it comes to antivirus restrictions, good to know one more troubleshooting technique.
But still how did it was allowing when run from development system? (Application was allowed in exemption list !!!?)

I think the enterprise antivirus system is more cautious whenever a exe is run.
