Subject: [WiX-users] Sequencing ProductSearch/RegistrySearch to get a
directory given an upgrade code
Is it possible to get a directory given an upgrade code? A ProductSearch
outputs a product code and a RegistrySearch can output the InstallLocation
given a product code but is it possible to schedule them so the
RegistrySearch uses the output of a ProductSearch?
