Currently, SAP offers two versions of Crystal Reports: Crystal Reports 2011 (CR2011) and Crystal Reports for Enterprise (CR4E).
I have seen lots of Crystal Reports confusion lately.
Here are some of the similarities as well as differences:
Have client side installed products (to your desktop)
Use the same key code
(as of Feature Pack 3) support relational data sources
Reports can be viewed and scheduled through the Business Intelligence Platform (BIP) using BI Launchpad
Some major differences:
Written in: C++ (Windows only) Java
Universe connectivity: UNV universe only UNX universe only
Crystal repository (shared objects): Yes No
Native ECC driver: Yes No – must use UNX Universe
