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;
