TMs Component Pack installation problems

In RadStudioXE3 when installing the new version of TMS Component Pack, all install well but when launching RadStudioXE3 multiple messages appear indicating that it can not load some packages.

After some test, marking and unmarking packages in the packages list, all goes well, indicating some problem in the order that packages are loaded in RadStudio. does someone have this problem too?
One more Question: What is the difference between libraries in bpl, DelphiXE3 and BuilderXE3 directories?
