I was getting those errors too some time ago. From what I learned those might be caused of different soft conflicts, like u have loads of MV C++ stuff installed, several installations of .NET etc etc. I tried to install FFXI with all the expansions and it crashed with error while installing some old DX version. It completely KILLED my system, nothing helped, BOSD every now and then. I simply reinstalled Windows - no launcher problems have been spotted for 5 monthes so far. In short - the less garbage installed, the better. Not very useful I know, but internets are helpless against those kinda errors, so windows reinstalling is the only solution I know.
