In certain scenarios users may receive an Error -30000 message when viewing images through the PaperVision Enterprise website. This may be a result of the anonymous account having all the necessary permissions and rights; but the images are stored at a different location from the Web Server. In some scenarios, the images may even reside on the same physical computer but are being accessed over the network using UNC paths. This type of configuration requires that the “ASP.NET Impersonation” option be enabled for IIS versions 7.5 and higher.
As of 6/14/2011 Microsoft released a critical update (KB2530548) for Internet Explorer 9 that addresses the issue stated below, and manually adding a registry key may no longer be required.
Also, PaperVision Enterprise version R75 no longer requires this registry change.
When a user attempts to use PaperVision Enterprise ActiveX controls, such as the document viewer, workflow viewer, and administrative controls, Internet Explorer 9 appears to lock up and can only be closed via Task Manager.
