Have you tried using the deployment wizard to find which files need to be deployed with it, extracting them then adding them to your install package? To install Crystal Reports, run Crystl32.exe. The location of Crystl32.exe depends on which version of Visual Basic or Visual Studio you own. In all cases, it is in the following relative path:
\Common\Tools\VB\CrysRept\Crystl32.exe
