Hi Marco,
If this is a web form application you'll have to apply the license key trough code in the web form constructor for example:
[C#]
using Nevron;
...
NLicense license = new NLicense("XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX");
NLicenseManager.Instance.SetLicense(license);
NLicenseManager.Instance.LockLicense = true;
...
[Visual Basic]
Imports Nevron
...
Dim license As New NLicense("XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX")
NLicenseManager.Instance.SetLicense(license)
NLicenseManager.Instance.LockLicense = True
This should get rid of the evaluation watermark.
Hope I helped - let me know if you have any questions or meet any problems.
Best regards,
Bob
