I've got an installer with a couple features, and they can either all be installed on one machine or on multiple machines. The features write values to the registry to auto-populate properties on upgrades, however some of the features use the same properties (database location, for example). What I ended up doing was writing several registry keys for this same value with slightly different names (e.g. Database_A, Database_B, Database_C). To pull these values out of the registry, I have a bit of code like this:
<Property Id="Database"> <RegistrySearch Id="Database_A" Root="HKLM" Key="$(var.RegistryKey)" Name="Database_A" Type="raw" /> <RegistrySearch Id="Database_B" Root="HKLM" Key="$(var.RegistryKey)" Name="Database_B" Type="raw" /> <RegistrySearch Id="Database_C" Root="HKLM" Key="$(var.RegistryKey)" Name="Database_C" Type="raw" /></Property> However, I recently added some code that had to a similar thing (read a property written by two features), and did it by reading in two separate properties and then using a custom action to overlay the values: <Property Id="Path"> <RegistrySearch Id="Path" Root="HKLM" Key="$(var.RegistryKey)" Name="Path" Type="raw" /></Property><Property Id="Path2"> <RegistrySearch Id="Path2" Root="HKLM" Key="$(var.RegistryKey)" Name="Path2" Type="raw" /></Property> ... <InstallExecuteSequence> ... <Custom Action="OverlayPath" Before="SomethingElse"><![CDATA[Path2<>""]]></Custom> ...</InstallExecuteSequence> ... <CustomAction Id="OverlayPath" Property="Path" Value="[Path2]" /> This second approach also works. So my question is, which is the preferred method? Multiple RegistrySearch elements for one property is certainly cleaner, but I couldn't find anything clearly defining the expected behavior.
