Ok,

- Version of Crystal reports?

BuildVersion=13.0.2.469.Cortez_CR4VS

- Version of Visual Studio?

VS 2010 premium

- Win or web app?

The problem is at runtime when loading crystal report assembly and is displayed in the Immediate window.

Not sure what your code looks like, but see the following;

If none of the above helps; did you ever install CRVS2010 Beta?
