I am writing on behalf of the company I am working with.
We currently are working with Groupdocs.Web.Annotation.dll version 2.1.1, and are utilising the Viewer class to configure aspects of the GroupDocs viewer within an MVC.Net (22.214.171.124)application.
The viewer works fine and renders PDFs as required within our product, however we are constantly prompted that we are running under a trail licence of the product, despite having a valid licence file.
I have confirmed that the licence file is being referenced correctly, and the file path given is correct.
The licence file is referenced by:
Where the licence file path has been pre-validated as being present on disk.
A new validation check has been added: Viewer.IsLicensed, which always returns false. When rendered, the document viewer is rendered with an orange toolbar which indicates that the viewer is being under a trial licence.
After opening and checking the licence file (as it was not me that purchased this licence), I can confirm the following, which I am hoping will be of some use in answering my query:
GroupDocs.Viewer for .NET
The only think I can think of is that the version of .web. and that of the licence is different. After updating to use GroupDocs.Viewer 3.0.0, I have come across a number of issues, including that I am unable to find a reference to the Viewer class - which I have noted as being removed in version 3.0.0. Unfortunately, we are not authorised to alter too much of the existing code, given that it "works" (management joy).
Are you able to shed any light into this situation and offer any advise on how to proceed?
