I receive this error when walking through the Quick Start via the online help.
I also tried by creating a new XML report (A basic listing report based on SELECT * FROM tbl.)
As a just in case, I included references to C1Report, C1Report.CustomFields, C1Chart, C1BarCode and still receive the message.
I have updated to the latest version 3.5.20153.223.
This is running under the .NET 4 framework.
Any potential direction to resolve is appreciated.
