DuplicateFile table with GAC

My installer has grown very large b/c of file duplication. Some of our DLL's are in two places (local and GAC or l开发者_StackOverflow社区ocal and system32 folders). How can I use the DuplicateFile table or other Installshield mechanism (installscript?) to duplicate the file in the GAC? It's the same file that needs to be copied to two locations but I only want it in the installer once because of its size.

My project type is actually Installscript MSI.

Hopefully my request is clear. Thanks!

The DuplicateFile table doesn't support deploying to the GAC because MSI doesn't uses a different pattern to deploy to the GAC then most folders. It uses MsiPlublishAssemblies which interacts with Fusion.

You have to declare 2 components ( 1 for normal and 1 for the GAC ). If size is a concern for you, WiX has a feature called smart cabbing which can create your cab and stream it into media with multiple file rows sharing the same storage.
