I have an existing VB6 application distributed to client using the Microsoft Visual Studio Installer 1.1 (VSI). The .Msi file has been installed by the client.
Subsequently, I have changed the VB6 code and need to give the client an upgrade. The upgrade consists of 2 files ...
A) The new .exe file(to replace the existing one).
B) An .ocx file to be copied to the client's windows directory.
I do not want to uninstall and deploy a fresh .Msi.
Is it possible to create something like a "Patch1.Msi" or "Patch1.Msm" file or similar? VSI doesn't seem to have some way to do upgrades.
