Forget passive for a moment. Install the MSI file. After it's installed,
try to install it again. You'll see a maint dialog as LoZ mentioned. The
default is Repair. It does not install it "again", whatever that might be
thought to mean. When you run without showing UI all that happens is that it
takes that default and does the repair. It's not even looking at your MSI
file, it's using the cached one in Windows\Installer.
