I want to add preinstall registry checks. This is to check if the pre-requisites are already installed in the system. If not, the installation should display a message and abort.

I added the checks but they dont seem to work. Please let me know if I am missing something.

The snippet I added is :

            <customErrorMessage>SQL Express installation not found.</customErrorMessage>
            <name>Microsoft Sql Server</name>
                    <name>Microsoft Sql Server</name>
            <text>The status of .NET installation is ${dotnet_autodetected} and status of SQL Express installation is ${sqlexpressCheck}</text>
I get a message saying : unknown variable ${sqlexpressCheck}

I don't know if the formatting is wrong here, but are there path separators between HKEY_LOCAL_MACHINE and SOFTWARE?

The problem must be that the rule in the <registryGet> action does not match (the key does not exists) and so, the variable does not get defined.

I believe the key should be: <key>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Sql Server</key>
