I have the following scenario: I have a manufacturer MSI File, with "Files compressed as CAB and CAB integrated into the MSI". Now I need to create a MST File for this installation and add a few custom config files of ours to it. What I want to come up with, is the original MSI, a CAB-File containing my additional files and an MST which modifies the MSI, that it will use the CAB file.
But what happens, when I open the MSI, add the files and try "Save as MST" from the build menu is, AI tries to extract all files from the MSI and compress them again into a "Setup.CAB" (in addition to the CAB1.cab I wanted created).
When trying to install with the MST, I have to have this setup.cab with the installation, despite the fact, that the manufacturer MSI is still containing all files. This behaviour is...suboptimal.
Is there a way to add files to an "Edit MSI" project without touching the files the manufacturer of the software has already build in the msi? Just adding an extra Cab?
