We'll probably just go with the hack-ish solution for now - do a FileSearch in the c:\windows\assembly directory.

This sounds like a slightly hard problem. I think you might need to either
have a CA that calls GACUTIL -l and tries to capture the output of it
somehow to determine if the assembly is there or have a .NET CA that
attempts to load the assembly based on its full name and see if that works,
returning a value based on that.
Ick.
Let us know what you come up with.
This does sound like a helpful feature for the WiX 3 NetFx extension to
support. :)

Subject: Re: [WiX-users] Search for a GAC component
Sorry, bad choice of words there. I really should have said "assembly", not
"component". The check would be for a third-party assembly, to ensure that
the prerequisites for our product our installed before they can run our
installer. Sounds like there's nothing there for that right now.
Thanks,
Kevin

When you say "component," are you asking about an MSI component or are
you looking to detect any assembly regardless of how it was installed?
For the former, <ComponentSearch> will do. There isn't a way to detect
assemblies generically -- though if you wanted to write one, I'm sure it
would be appreciated.<g>
