RegistrySearch vs util:RegistrySearch in Burn

Question

I am using Burn to build a WiX bootstrapper. I realized that RegistrySearch as shown below does not actually search the registry. I used Process Monitor to monitor registry

Answer 1

Property and RegistrySearch are concepts for .msi packages. Bundles (bootstrappers) aren't processed by the MSI engine so they have other concepts, like Variable and util:RegistrySearch. They're similar and generally bundles have more functionality in searches than the MSI equivalent.
