LVRTE2013 and VISA5.4 error 0xBFFF0072

[SmartBMS]

I build a runtime application (*.exe) using the development LabVIEW 2013-64bit on a PC running Win7-64bit.

I installed on another PC running Win7-64bit: LVRTE2013-64bit, NI-VISA 5.4 and my application. The application use a Serial com port. The application works, but when tries to open VISA resource, it generates an error: “NI-VISA 0xBFFF0072, The resource is valid, but VISA cannot access it.”

My application use VISA search to generate a list of available COM ports and this point works very well. When tries to open a Serial Port, is generate the error.

MAX also recognize the serial ports but when I try to change settings, it generates the same error report.

What can I do?

Thank you,

Cristian

The os only allows one process at a time to use a port. MAX cannot run at the same time as your exe, LabVIEW development, etc. What else might be running? Have you checked task manager?
