There is an alternative approach here

might be useful.

I am trying to do the almost famous replaces on SQL Scripts before running
them. I only have a few days to do that, and cannot get into writing a
generic C++ as an add-on to the existing SQL Extensions.
There are a bunch of SQL scripts, which I cannot modify, and they have a lot
of replaceable %Parameters%
I know it's ugly, but copy+pasting several 6K row scripts into SQLString
elements is not an option.
I will really appreciate, even more than usual, if there is a nice
workaround at hand.
Thanks,
Eitan

You can't do that. The MSI is readonly.
What are you trying to accomplish?

Subject: [WiX-users] Modifying the MSI file at runtime using DTF
Hi,
I am trying to modify the MSI file at runtime, basically, I am running a DTF
Custom Action (immediate, after InstallInitialize) that extract certain
Binary files, modify them, and save them back into the MSI file.
The problem is that I cannot save the files back to the binary table. I am
using the sample provided with the DTF documentation:
db = new Database(session["DATABASE"], DatabaseOpenMode.Direct);
...
session["DATABASE"] gives me the actual msi file (from the Windows\Installer
folder).
But, I am getting an ugly error:
Microsoft.Deployment.WindowsInstaller.InstallerException: The system cannot
open the device or file specified. Database="C:\WINDOWS\Installer\e659b.msi"
Looks like the database is locked.
Please, I would like to know if what I want to do is doable, and if yes,
what is the correct approach?
Thanks in advance,
Eitan
