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?
Thanks
