MSI isn't updating an existing VB6 DLL

A setup project includes C# assemblies and a VB6 DLL (vendor supplied com
object). It's updating the assemblies just fine, but isn't replacing the
VB6 DLL. The file does get laid down if I run the MSI again to repair.

In the setup project, the Register attribute is set to vsdrfCOMSelfReg. The
version of the updated file hasn't changed - it's still 1.0.0.0.

Any ideas? Thanks.

MSI won't replace a file on disk if the incoming file version is the same as
the installed version. Repair shouldn't make a difference to that. If the
file versions are the same, surely the file is the same? That's the
assumption that installation programs make. Here's the MSI doc.

On the other hand, if it's not really a replacement (for example because
you're using RemoveExistingVersions to remove the prior version of the
entire product) it is supposed to be replaced.
