MsiConfigureProduct seems right to me.

I recently found that if you use setupbld to chain multiple msi installs
together and one install fails the rollback is broken.
I have fixed this locally, but found that there were two ways to address it.
The rollback code call ConfigureMSI, but only supplies the product code. In
the code for CONFIGURE_ACTION_UNINSTALL the call to ::MsiInstallProductW()
fails since wzMsiPath is null. The first way to fix this would be to pass in
the path
to the MSI. This could get tricky I think based on whether the MSI was cached
or not and if the temp file has already been deleted.
The route I took to fix was to leave the calling code as is and change the
handing of CONFIGURE_ACTION_UNINSTALL to simple call ::MsiConfigureProductW()
passing in the provided wzProductCode and INSTALLLEVEL_DEFAULT,
INSTALLSTATE_ABSENT.
Testing this with an installer created from two MSI installers, where the
second install is guaranteed to fail shows that the previous install is rolled
back.
Which of the two methods described would be seen as the choice fix?
I would like provide a patch for this fix, knowing that Burn is setupbld’s
replacement. I think others could benefit from this. I have been working with
burn, but have not yet become comfortable with it enough to adopt it. There are
situations where I would like one installer, but have the chained packages
show individually under Add/Remove programs.
