I'm trying GroupDocs.Annotation .NET library. First I launched it on Windows 7, IIS 7. Then I tried to transfer the same site to windows server 2012 R2, IIS 8 and I got some errors saying that GroupDocs handlers does not respond, e.g. "/document-viewer/GetScript?name=libs/jquery-1.9.1.min.js&_=1430727712450".
I can see these handlers under Handler Mappings tab in IIS 8 but for some reason they do not respond.
Is there some kind of incompatibility with windows server 2012 or IIS 8, or maybe I'm missing something ?
