How do you register a Win32 COM DLL file in WiX 3?
The easiest way (and Rob M will rant and rave about how this is wrong) is just to use SelfRegCost=1 on the File tag for the DLL.

.net reference specificversion true or false?
This answer is going to be based on the assumption that you are versioning your dlls. If you set SpecificVersion to true (which is the default when adding a reference), then the project will reference to that dll with a particular version (say for instance 1.0.0.0). If, at a later time, you’re given a new … Read more
