The i1Pro Bundle ships in the standard i1Pro package, which includes the i1Match master installer CD. This CD contains all of the programs for i1Match, i1 Share, and i1Diagnostics.
In most cases, you won't need the i1Match software because ProfileMaker will perform your standard profiling needs. However, you may need the i1Share and i1Diagnostic programs on occasion. Including i1Match installer makes it easier to add i1Match modules later because you only need to enter the license code to unlock them.
