The Boost11 issue may be related to MC7, the plug-in is part of it's core installation by design. MC7 is now based on the new version of SONAR.
It's resetting the Boost 11 file path entry in the registry hive, rather than honoring it on every install,
and the DLL version is incrementing upon each monthly release even though there is no code change.
This means boost11 is always being reinstalled as a new version on every release, and not even honoring the registry file path. That is
two bugs from a developer perspective. It's probably the way they are building their solution in Visual Studio and dodgy upgrade logic.
If it's part of the core installation by design then it either needs to be separated from the core, or the core installation logic needs changing but that is an entirely separate matter to the behaviour.
