First, you'll need to find the Component GUID that installed the file you are interested in. There is no API to do this so you'd either have to know the Component GUID or do a bunch of MSI File/Directory table resolution. I recommend just knowing the Component GUID because it shouldn't change once the Product is installed.

Then you can use ::MsiEnumClients() to find the ProductCode. With the ProductCode in hand now you can get all kinds of information about the installed MSI.
