That comment directly above is in the context of CCC.
Please don't get this categorised as a CCC issue, we all know it needs work.
CCC does install to the correct areas after you've installed Platinum and have your registry settings set correctly with the exception of the Dim Pro Installer, Rapture and Boost 11 in the latest update. The issue is NOT with CCC it is with the installers.

Even if the registry has been modified CCC will still make changes according to running the default installer for every individual program element.
As far as the lights are concerned - yes they ignore the registry (for example Dim Pro and Rapture) and there's no real logic.
In regards to installation I don't see this at all in the latest update if the registry settings are set correctly apart from the 3 installers I mentioned. Might want to check them. If you see other areas I may have missed let us know in regards to this update.
In regards to Boost 11 they are clearly building it as part of Sonar package rather than stand alone hence the version numbers are incrementing as though it's a new release on every update - this is a developer error. And regardless it's resetting the registry path as though it's a brand new install every time, there is no upgrade logic.
