I’m trying to run a GroupDocs demo project but getting an error (please see attached file). Do you know how can I fix this error.
Thanks for your response
I run the sample for .NET version in visual studio 2012 and demo project is GroupDocsViewerWebformsDemo
I downloaded GroupDocs trial dll and reference it intoto the demo project but still got the error. I did not change any code in the demo projects
What do I need to do to run the demo project?
