I'm using Viewer version 2.14.0 and experiencing an issue in a MVC4 project where resource files needed for the Viewer to display correctly do not load and the UI looks broken because of that. The toolbar buttons are missing images, the loader spinner does not show, etc. Aside from that the viewer seems to be working. I am able to load documents and view them, the toolbar navigation controls work and I can navigate the pages by clicking next and previous page, etc. The thumbnails show and the pane slides in and out.
When I look at the HTTP requests made by the page I am able to see that requests for JS files are successful, but requests for the fonts and images are not. IE
GET /document-viewer/GetScript?name=libs/jquery-1.9.1.min.js result 200
GET /document-viewer/GetScript?name=GroupdocsViewer.all.min.js result 200
GET /document-viewer/fonts/PT_Sans-Web-Regular.woff result 404
GET /document-viewer/images/sprites.png result 404
