One option I have used is to write a .Net 4.0 DTF custom action that allows you to open the 64 bit registry from a 32 bit CA using "RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64)". No good if .Net 4.0 is not on your target but there are ways to do the same thing in native code or interop. Neil Neil Sleightholm X2 Systems Limited n...@x2systems.com <mailto:n...@x2systems.com>

We are currently using the v3.5 RC build. We have a 32bit installer that detects AppFabric using the following bit of WiX code: <Property Id="APPFABRIC"> <RegistrySearch Id="AppFabricRegistry" Type="raw" Root="HKLM" Key="SOFTWARE\Microsoft\AppFabric\v1.0" Name="ProductVersion" /> </Property> <Condition Message="Microsoft AppFabric was not found on this machine. Please install Microsoft AppFabric."> <![CDATA[APPFABRIC <> ""]]> </Condition> This works fine on 32bit systems but we get an error when the installer is run on x64 systems because AppFabric registry key only exists in the 64bit hive. If I try to use the Win64="yes" attribute on the RegistrySearch element then I get an "error LGHT1076: ICE80". All the searching I have does seems to suggest that 32bit packages can't access 64bit hive. Our application and the installer are both 32bit only. Of course without the RegistrySearch condition the installer works just fine on x64 systems but we would like to be able to detect AppFabric. So far writing an unmanaged (or managed) custom action seems like our only option. Is there a way to achieve this without a custom action?
