OPC server 2016

[Plumos94]

Hi !
I was using the trial version of LabVIEW until I decided to buy the full 2025 version with some programs. I installed and activated all the licenses but as I use the OPC server, it connects and starts a timer that begins at 2 hours and when it reaches 0, it says the demo version has ended. How do I stop this, since I already bought and activated the license, etc.?

By any chance your activation didn't work?

Open NI License Manager and double check.

I'm not sure but the NI OPC software was originally part of the LabVIEW DSC add-on but they changed that into a separate license at some point.

You will need to get a separate license for the NI OPC Server. It is not part of the standard LabVIEW license or even the LabVIEW DSC toolkit.

The part number is/was 782278-35 but while it is possible to search for that and get a product link in the search results, that link points into nowhere.

The Contact us link points at https://www.ni.com/en/forms/sales-inquiry.html but I think it will not be to helpful. your best bet is to call them. But the license may be not an active product anymore and even if it is, it will be an additional purchase, not part of the standard LabVIEW license unless maybe if you are still on one of the LabVIEW Developer Suite licenses that used to be available in a long ago past for NI Alliance Members.
