I also run into a GUID and "*" related issue:
I have all of the components use * as the GUID. For one specific component,
however, I always get an "xxx component has a duplicate GUID: {...}" when I use
Visual Studio 2008 to compile it. I'll have to give it an actual GUID, then it
compiles okay. Interestingly, in our build server, we don't have this
problem(we use command line compiler in build server). Is there any chance that
Wix for Visual Studio 2008 has a bug regarding this GUID generation?

Subject: Re: [WiX-users] Heat and GUIDs
the help about -ag says: "autogenerate component guids at compile time"
I assumed this would mean that each time it is compiled a new guid was
generated.
If in fact the guid is static as you say, it must be recorded somewhere
(all the file has in it is "*"), ie wix would have to know what guid was
used for that component last time we created an installer and reuse it.
My question is how would it know? or more simply where is the guid recorded?
