Using Visual Studio for putting together my MSI package, I'm having a hard
time setting up a so called "Launch Condition" to check if Web Services
Enhancements 2.0 SP1 is installed.  It wants a Component Id which the
documentation says you should find using something like MSI Spy Tool to
locate.

That sounds vague enough as it is, but the Platform SDK doesn't seem to
include such a tool.  My best shot is Orca, but where is the ID I'm looking
for?

Any ideas, or is this simply one of those things that I must program my way
out of with a custom installer in .NET?

Thanks,

Niels
