This might also be titled "How do I launch the modification of a Burn
install from the command line without the Burn executable?" or "What's the
Burn equivalent of 'msiexec /X ProductCode'?"
I have a program, A, which ships with two optional programs B and C. All
have functioning MSI installers. I use Burn to manage the installation of
A, B and C.
On first install, the user is asked if they want to install B and C. All
works fine.
But subsequently, the user should be able to install or uninstall B and C.
The user can of course do this from Programs and Features, using Modify.
This relaunches my Burn executable.
However, I want the user to be able to trigger this functionality from
within Program A - that is, I don't want the user to have to launch
Programs and Features, find the bundle, and click Modify. I want to have a
button in Program A that will do it, launching Burn.
But how? If it was a single MSI, I could shell "msiexec /I {ProductCode}".
I know the ProductCode because that's a property of the MSI. So I can save
and use it as required.
But a Burn bundle doesn't have a ProduceCode. It has RelatedBundle, but
there's no msiexec argument for that.
If I check for the bundle in the registry, I find the information I need in
an entry in
HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall, which
is perfect. There's the line I need to launch Modify, it calls the cached
bundle executable in "ProgramData\Package Cache". But how do I get that
line?
How do I launch the Burn package manager for my package from within a
program of my package?
