As per the note:
The BW Business Explorer Frontend is available only in 7.x version with the SAP
GUI 730 DVD Compilation 1 onwards. The BW Business Explorer 3.5 version is no
longer available with SAP GUI 730 Compilation 1 onwards including Compilation 2
& 3.
The BW 3.5 frontend add-ons are Business Explorer frontend for
