There are differences between what is included in “ChemBio3D Ultra” (what is currently being licensed by the Library- thank you!) and "ChemBioDraw Ultra", which is the product that has at one time been site-licensed at Cornell.

Also, there are more elements which work on a PC than work on a Mac. Details below.

ChemIT's characterization of the naming and licensing issues, as of August 2014

PerkinElmer markets four suites (Ensembles) with the word "Ultra" in their names. This may explain the (continued?) confusion by folks communicating about their products!
