License defaults to trial in versions greater than 5.58.451

Hello,
thank you for feedback. And you are right, in a way. If you know that this can happen, you can check it right away, without having to wait for 30 minutes - see

opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...0Obtain%20serial%20number.html

If the serial number (in your case, after the registration) comes out as 111111xxx, the effective license being used is a trial/demo license.

But, of course, if you do not explicitly check for it, you would not know. I understand your point, will think about it, and will see if it can be improved. Refusing to run altogether was an option we considered, but believe me, in other scenarios users would not like it either.

Re

"And a reason for rejection of the license should be given."

: In latest version, the exception after the allowed run-time lists a "dropped license" serial number. and the last covered released date. So this part is already resolved.

Re

"How can us users know what versions the license is valid for?"

: In the License Manager (or via the code), you can view the "Release date covered" field - again, assuming that you actually know about it and actively check it.

Thanks for the feedback again
Best regards

That explains it, thanks for the quick reply.

I would like to note that defaulting tot the trail license silently is unusual and impactfull. Who runs dev tests for more than half an hour to check for such things?. I now know there is a workaround to check if the license is trial or not. If you try to register a specific license and it doesn't work it should probably give an exception instead. And a reason for rejection of the license should be given. How can us users know what versions the license is valid for?

Hello.
The behavior is correct.

You have purchased a license without an upgrade assurance. This means that it covers the version that was current at the time of purchase, and any version released in 60 days following that.

QuickOPC versions, together with their release dates, are here: kb.opclabs.com/Versions

You need a version upgrade in order to be able to use newer versions.

Best regards

We are using the RegisterManagedResource method and have a valid license. With the latest version (5.59.1055) of the nuget package, the license defaults to the trial license. It works correctly with version 5.58.451. Everything else should be correct since it works with the lower version.

It's a Visual Studio project using the nuget package with target framework .NET 5.0. Tried with other dotnet frameworks but has same results.
