Open "msi" file via Automation interface

[ipcquasar]

Hi!
I am using InstallShield 2010 via Automation interface on C++ Builder 2010.

When I try to open existing "msi" package:

Variant ISPrj;
ISPrj = CreateOleObject("ISWIAuto16.ISWiProject");    
ISPrj.OleProcedure("OpenProject", "d:\\tmp\\httpd-2.2.16-win32-x86-no_ssl.msi");

I get an exception

"Unable to open file: Please make sure that the file is a valid InstallShield Developer project"

Where did I mistake?

Ps. If I open the this "msi" file via GUI it opens.

Thank you

Automation interface is for InstllShield project(*.ism), not *.msi.

If you want to open existing "msi" package, you can try Orca.

Hope this helps!

Thank you Kevin.Wan for quick answer.

If you want to open existing "msi" package, you can try Orca.

I have already tried Orca before InstallShield. It doesn't have COM interface.
My aim is to create application, which correct two msi packages and merge them into one msi package in automatic mode. Do you know other instrument, which help me with this task?

Kevin.Wan, As far as I understand I can't create *.ism project, add into some "msi" packages and save as msi. Is it true?
Why I can open msi via GUI interface?

PS. Sorry for my English.
Thank you

You can modify an MSI database using the Windows Installer automation interface. Check out the previous newsletter article "Using MSI Automation to Modify a Developer Project".

Hi! It's me again.

I overlooked that I need to edit not only database, but files to(((
How can I edit set of "files of MSI package" (not MSI files, such as icons, install dialogs, etc.)? Is it possible via automation interface/COM?

Thank you
