Hi, I red a lot of threads about that problem, but I still stuck at the same point.
During the development of my application on Visual Studio, everything was working well but just after the deployment (On the same PC) my Crystal Report stopped to do the job and I get this error : (Sorry, that's in French)

Name: Crystal Error.PNG Views: 2551 Size: 33.5 KB

So, after reading some threads, I tried to solve the problem, I download and install the runtime.net of crystal report but I still get the error
I heard about adding merge module and I'm trying that for now but I doubt that it will work

If you already had that problem, I would be happy to read how you resolve it, have a nice day !
