Just some advice for those of you who are new to SAP and are looking for the supporting documentation to the SAP Crystal Reports runtime engine.
If you don't use Eclipse as their primary IDE for java development or you are using Eclipse on a non-Windows operating system then you will be better off downloading the All-In-One Installation as it contains all the documentation, including the Designer Guide, the Development Guide, and the SDK Reference - both current and legacy runtime libraries. The All-In-One Installation runs only on Windows, but the SAP Crystal Reports runtime engine is cross-platform.
If you do use Eclipse and are on Windows don't both with trying to do a Manual Install as it's too hard work trying to get all the dependencies resolved, especially if you are using a newer Eclipse release than the version available in the All-In-One Installation.
