If yo look at Attributes column of Component Table, If this bit (msidbComponentAttributesSharedDllRefCount) is set, the installer increments the reference count in the shared DLL registry of the component's key file. If this bit is not set, the installer increments the reference count only if the reference count already exists. To ensure proper reference count, it is set to Yes by default.
Tsung, Thanks for the reply, that is sort of inline with what I was thinking. Do you know if there is anyway to set this to "Not Shared" as the default action?
Unfortunately, I don't. I remember seeing others asking for the same thing on the forums, but I don't remember seeing a solution. Someone did recommend having a script to automate the process of changing it from Yes to No on all components. It may be something to consider if you have more than a handful of components.
