Has anyone had the problem of creating a web part using Crystal Viewer, the web page works fine as long as the user is Admin. If a non Admin user tries, I get the Unsupported Operation. A document processed by the JRC engine cannot be opened in the C++ stack. I set full control security on the report folder and \Windows\Temp\ I also tried the ProcessMonitor program looking for access denied errors, none were found. So there must be some security issue somewhere but I do not know where. SharePoint 2010, Visual Studio 2010, Crystal Reports 2011
