The program is from the original Rapture. In the original Rapture, the program is in "01 - Sequences." If the original Rapture was installed
before RP it would show up in "Rapture Classic User Imported" in "01 - Sequences" too.
The "Rapture Classic Factory Library" installer is RaptureClassic_003.exe (Rapture Classic under Rapture Pro in the Command Center) contains this program. Unlikely it was dropped. Dimension Pro or any RP installers for DP would not contain this program.
This program was not sold separately. It is part of both Rapture and Rapture Pro. I see the program in both RP libraries and in the original Rapture.
