I have just purchased Spire.Doc Pro Edition Version 4.2.1 and I'm trying to license it using the file that was sent via email. I have followed the instructions but I continue to get the watermark. I used one of the examples "ToPDF" in Visual Studio 2010. I simply added the file to the project by placing it in the folder and setting the Build Action property to "Embedded Resource".
I even tried to set the license file location with this...
Spire.License.LicenseProvider.SetLicenseFileFullPath("C:\Program Files (x86)\e-iceblue\Spire.Doc\Demos\VB\WinForms\05_Convertors\ToPDF\license.elic.xml")
Any ideas how to get this resolved?
