Sorry, my bad. I didn't realize you were talking about the
util:RegistrySearch. My answer was about the MSI based RegistrySearch.
Using util:RegistrySearch is explicit. If you say Win64='yes' then the
search is 64-bit and vice versa. You can ignore the fact that the Burn
engine is 32-bit. It matters none.
