I need to run some queries on a MSI database from an app after it's been installed. Looks like that starts with MSIOpenDatabase(), which requires a path to a .MSI file. However, I'd like to use the cached MSI file in [WindowsFolder]Installer, as the original MSI file might not be available. So, the question is, how does an app determine the cached MSI file it was installed with? Is there something more elegant than iterating and opening each file in the directory, checking if it matches the app's product code?

Try using MsiGetProductInfo and query "INSTALLPROPERTY_LOCALPACKAGE".

If that does not work, then you can open the registry and find the value from there.

Thanks, that was it.

I thought I'd learned to RTFM by now.
