A document processed by the JRC engine cannot be opened in the C++ stack

Question

I have created a crystal report in vs2010 with .net4.0. when I publish the website it throws the error \"A document processed by the JRC engine cannot be opened in C++ stack

Answer 1

I have found another set of circumstances under which this rather unhelpful error appears.

If you F5 to run/debug your web application in Visual Studio BUT still have the the report open in Crystal Reports (2011), you will get the error.

Drove me nuts for about an hour today!
