Hi, Igor. I have seen many posts in Stackoverflow and in this mailing list with the same question as mine. Seems like there is no other way except creating custom action. I've viewed .msi with Orca. WiX does it's job: if I skip RegistrySearch/@Name attribute it fills it by null. It's a limitation of Windows Installer technology. There is no difference between "no key" and "default value of the key". "This means that there is no way to detect the presence of a key that has no default value: the result will be the same whether the key is missing or it is present but has no default value" (http://etutorials.org/Programming/Mastering+visual+studio+.net/Chapter+6.+Setup+and+Deployment/6.11+Launch+Conditions/) Thanks for the link. I'll try to create custom action using Votive.
