Why would MSIGetProductInfo return 0x80070645 for product obtainedvia MsiEnumRelatedProducts?

I have a piece of code that enumerates products via an upgrade code
(MsiEnumRelatedProducts). Then I call MSIGetProductInfo. Sometimes the
latter fails with 0x80070645 - "this action is only valid for products
that are currently installed".

Is this normal? Am I missing something? MSDN says that
MsiEnumRelatedProducts only returns intsalled and advertized products,
so I would expect MSIGetProductInfo not to fail.

Why not read MSDN for that function? It says
the same thing. Maybe you're thinking of
MsiGetSummaryInformation?
