Create msi using GNOME/msitools

Question

I am running Centos7 and my ultimate aim is to modify an existing msi(Microsoft Installer) file using https://gitlab.gnome.org/GNOME/msitools...

but before doing that wanted to see whether I could extract an existing msi file and recreate the same(without any modification) using this msitools by doing following..

1. Extract existing msi table and file contents using tools like **msidump**, **msiextract**

2. Create the msi using **msibuild**

But I didn't get the expected msi file after second step, and got following error while trying to extract.. "libmsi_record_get_stream: assertion 'LIBMSI_IS_RECORD (rec) failed'". It is clear that I didnt create msi properly.

Can someone help me what should be the series of commands that should be used to just extract the existing msi and recreate the same using msitools.

Thanks in advance !
