Those Crystal Reports runtime files seem to be missing. I would assume you need to deploy them along with your product.
I haven't used this component for a long time, and I have never had to download it, but have a look here: Install sap crystal report as prerequiste in clickonce deployment. You will need to adjust the paths for new versions of Visual Studio - depending on what version you are using.
It seems this page is what they refer to. A real mess by the looks of things. Maybe have a go at that and see if you get anywhere. I can't test this right now.
