UnauthorizedAccessException when using a ViewerImageHandler's GetPages Method

GroupDocs.Viewer Product Family
1

I’m using GroupDocs.Viewer version 18.5.0. This issue did not occur in the version I upgraded from: 17.12

HttpPostedFileBase file = Request.Files[0];
Stream stream = file.InputStream;
byte[] attachmentData = attachmentData = new byte[file.ContentLength + 1];
stream.Read(attachmentData, 0, file.ContentLength);
ViewerConfig viewerConfig = new ViewerConfig() {  };
ViewerImageHandler viewerImageHandler = new ViewerImageHandler(viewerConfig);
List<PageImage> imagePages = viewerImageHandler.GetPages(stream, adminPortalViewModel.FileName);

When run on my server I get the error “Access to the path ‘c:\windows\system32\inetsrv\vs.bin’ is denied.”
When debugging locally in Visual Studio 2017 I get “Access to the path ‘C:\Program Files (x86)\IIS Express\vs.bin’ is denied.”
When I run VS2017 as an admin I do not get an error. Ideally I would like to specify a path to use rather than have it decide for me and use a system directory.

Thanks for your response.

Please try using the following configuration and check if it works at your end.

ViewerConfig viewerConfig = new ViewerConfig()
{
          CachePath = "D:\\cache", // any folder of your choice
          EnableCaching = true,
 };

ViewerImageHandler viewerImageHandler = new ViewerImageHandler(viewerConfig);
...

Hope it helps.
