64 bit version of Oracle Waveset gateway.exe

Hi all,

    I'm looking for a 64 bit version of the gateway.exe service. I have OW 8.1.1.8. Here is the gateway.exe.manifest file that comes with it.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1"
   manifestVersion="1.0">
<assemblyIdentity
            type = "win32"
            name = "client"
            version = "1.0.0.0" />
<dependency>
            <dependentAssembly>
                        <assemblyIdentity
                                    type="win32"
                                    name="PowerShellExec"
                                    version="1.0.0.0"
                                    publicKeyToken="6fc9804d812640ee" />
            </dependentAssembly>
</dependency>
</assembly>

And sure enough, when looking at the service using procexp, it's very definitely a 32 bit image. I am running on Windows Server 2008 R2 x64, and, because of other dependencies I need a 64 bit image for the gateway. Is one available?
