Windows 7 is not officially supported by National Instruments as it hasn't even been released. That means you won't get any official support from NI on this.

That said, does your computer actually recognize a serial port? Do you have an actual serial port, or do you have some sort of virtual COM port, or are you using some sort of adapter, such as a USB to serial port box? If it's any of the latter, the most likely reason is a driver issue which needs to be written to be compatible with Windows 7.

Windows 7 is not released. A version of LabVIEW for windows 7 is not released. A version of NI-VISA for windows 7 is not released. Wait until ms releases windows 7. Then wait untile NI releases versions of LabVIEW and NI-VISA that work with windows 7.

Oh...I see, so I have to wait new version for Windows 7 or try other com port drivers.

Thanks for solving.
