The type initializer for 'crystaldecisions.crystalreports.engine.reportdocument' threw an exception

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with. And that means we have no idea what code you are using to open CR. Since that's what is causing the problem, we need to know what your code looks like, and what values you are passing.
