We currently have the license for Spire.Doc Pro Edition. After installing the license file, I am able to generate the PDF documents from word document, without any issue. However, I noticed that whenever, I try to merge multiple pdf documents together, my merged document always gives me the evaluation warning message: “Evaluation Warning : The document was created with Spire.PDF for .NET.”
I am using the dlls (Spire.Doc, Spire.License, and Spire.Pdf) that I received along with my license file. Do we need to purchase Spire.Pdf Pro separately, in addition to Spire.Doc Pro?
