I have Nevron UI and Diagram components on a Winforms application. At runtime on the target PC, I get a message on the Diagram component, "...unable to find a valid license key...". The UI controls work perfectly.

I have tried the following code in the main form's constructor, with my developer license key. No help.

NLicense license = new NLicense("XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX");
NLicenseManager.Instance.SetLicense(license);
NLicenseManager.Instance.LockLicense = true;

Hello Billy,
Do you have separate licenses for the Diagram and the UI? If yes, you should also have two Desktop licenses and you need to apply them both programmatically. You can add multiple licenses in the license string with comma separation.

Hopefully this helps.

I purchased the diagram and UI together and have only the one license.

Make sure that you are configuring your Desktop license in code, not the Developer license.
If you still have problems, feel free to request a web meeting with the Support team.

That must be the problem, it was not clear to me that the desktop license is different than the developer license.
How do I get a desktop license?

Your licenses, including the Desktop license, should be available under the main Nevron.com account.

Yes thank you.
Sometimes I overlook the obvious
