ES and 64bit Windows Server 2008

When trying to start ES on Windows Server 2008 from the command line, I get the following error message:

Unable to locate a Wrapper executable using any of the following names:
H:\elasticsearch\bin\service\elasticsearch-windows-x86-64.exe
H:\elasticsearch\bin\service\elasticsearch.exe

I have verified that neither file is located under the bin\service directory (nor anywhere else under the elasticsearch folder) or in github.

Can someone direct me to the correct location? Or am I possible asking for something that doesn't exist?

I've done a write-up of an alternative way of running ES as a service on Windows x64 (could be used on 32 bit as well though):

Let me know if this helps.
