Hello,
thank you for the details.

The information I have leads me to a suspicion that there is something wrong with how you are embedding the license key.
Have you gone through the steps described under the Troubleshooting header on opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...esource%20License%20Store.html ?

Best regards

Oh, I see you have already tried the embedding the license. That is the right way to do it.

You then need to describe what actually happens. The full error message.

Hello.

The License Manager is for managing the license keys stored in the registry,

They license keys from the registry are used in projects that target .NET Framework, COM tools, and for features that "live" inside Visual Studio (such as Live Binding) in design time.

In your case (targeting .NET 5), you need to embed the license key in your project. See:

- opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...esource%20License%20Store.html

Hi,

We activated the license via LicenseManager(program) and used the OPCLabs library as usual, however in a .NET 5 application instead of .NET Framework as before.
After a little while we saw that the license stopped being active as was called a demo (it's a standard site license to my knowledge).
I then used your documentation to get any information about the active license via the code, and it returned it's version was 11...1120 (demo).
I tryed using the in code OPCLabs LicenseManager to activate a share it code as embedded resource, but still same result.
Any ideas of why this is occuring?

Best regard
Dang

Hello,

We are having dificulties with using our OPCLabs license on .net 5, I'm in doubt if this is due to the version of our license?
We have lost the receipt and don't know if it's with upgrade assurance, or if our issue is something else?

Best regards
Dang
