Thank you for your response. Maybe I'll try to describe the
original problem.
I have got an old msi installer and a set of msp patches which can be
installed on the top of this msi.
Msi/msp and content of these are not digitally signed. I have no sources
for this stack (ups!).

I need to sign the content of msi/msp, rebuild and sign msi/msp.
Now I have scripts which extract cab from msi, extract cab, analize File
table sign content,  update file size, hashes, build cab, replace cab,
build msi, sign msi:) it is a long way which shows how complicated msi is.
Everything works, but I need a similar way to do it with msp.

As I understand your answer, the "unpack-edit-pack"  proces is
technically possible, but there is no exposed switches/api to do it in
current implementation am I right?
