WiX RegistrySearch in all subdirectories
问题 I need to check whether an any version of some product is already installed. <RegistrySearch Id="MyId" Root="HKLM" Key="SOFTWARE\Company\{ANY FOLDER}" Name="MY_KEY_NAME" Type="file" /> Is it possible to use RegistrySearch for searching in all subdirectories? 回答1: AppSearch / RegLocator doesn't support recursion. You'll either need a custom action or change the way you store data in the registry. 回答2: To my knowledge and from the documentation I see nothing that points to RegistrySearch
