How do I reference the installed path of a file in a registry value?

Question

I want something like the following:

    <RegistryValue Id="Command"
                 Root="HKCR"
                 Key="myProgram\shell\open\command"
                 Type="string"
                 Value='"[SERVER_DIRECTORY]myProgram.exe" "%1"'
                 Action="write">
    </RegistryValue>

Where [SERVER_DIRECTORY] is the directory myProgram.exe is installed to (ProgramFiles64Folder\MyProgram). How can I do this?

Answer 1

It should work the way you tried. But you can reference myProgram.exe as [#myProgram] (meaning myProgram is the Id of a File element). See the Formatted type description for more details.
