I expect boost11 to behave the same as any other plugin during installs (where I put my plugins is irrelevant a bug is a bug). In a nutshell Cakewalk say they fixed the Boost11 installation issue in the Dorchester release notes but it isn't. If you use default path's it should not effect you although a new version of it seems to be built and overwritten on every release.
And Track templates seem to be crashing "randomlyish" if you are using multiple tracks (perhaps). People have validated the issue and is a PITA for me. Not sure if it's drummaps or not at this stage.
For further discussion probably best to stick to those threads.
