The installers are not only available in Cakewalk Command Center.
While possible, it would require a pretty big redesign of our delivery system as well as how the installers themselves are built. Lots of extra work for lots of people. More likely then not we may reconsider how the help itself is distributed longer term. Step 1 was to break it out from the Tutorials to reduce the overall footprint though, that way if you're updating just help you're not also downloading the tutorial content each time.
