ElasticSearch as Windows service - problem

Hi,
I have been running ElasticSearch on Linux and Mac OSX successfully
for a while. I was going to set it up on a Windows 2008 server as a
service. It is a 64 bit server.

I've set up elasticsearch 0.15.0, and I can start it and stop it on
the command line without problems.

I downloaded the elasticsearch service wrapper (http://github.com/
elasticsearch/elasticsearch-servicewrapper), and put the service
folder inside $ES_HOME/bin.

I also downloaded the Java Service Wrapper standard edition (as there
is no community edition for Windows 64 bit), and added the .exe,
wrapper.jar, and .dll.

When I try running "service/elasticsearch.bat install", I get the
following message:

C:\Website\App\elasticsearch-0.15.0\bin\service> .\elasticsearch.bat
install
FATAL  | wrapper  | Failed to load configuration.
Press any key to continue . . .

If I run it without the install option, I get a slightly different
message:

C:\Website\App\elasticsearch-0.15.0\bin\service> .\elasticsearch.bat
FATAL  | wrapper  | Unable to resolve the full path of the
configuration file, : The filename, directory name, or volume label
syntax is incorrect. (0x7b)
FATAL  | wrapper  | Current working directory is: C:\Website\App
\elasticsearch-0.15.0\bin\service\exec
FATAL  | wrapper  | Unable to resolve the full path of the
configuration file, : The filename, directory name, or volume label
syntax is incorrect. (0x7b)

Can anyone spot what I'm doing wrong?

Thanks!
OGG
