need separate Obfsproxy Windows binary

I am using Tor Expert Bundle in Windows. Adding obfs2/obfs3 bridges to torrc always get warnings like this:

[warn] We were supposed to connect to bridge 'xxx.xxx.xxx.xxx:xxxxx' using pluggable transport 'obfs2', but we can't find a pluggable transport proxy supporting 'obfs2'. This can happen if you haven't provided a ClientTransportPlugin line, or if your pluggable transport proxy stopped running.

Tor Expert Bundle does not include any pluggable, and as far as I know, obfsproxy does not provide separate binary neither, except the the whole big Tor Browser bundle. I would like keeping use "lightweight" Tor Expert Bundle with obfs support. Could you please provide separate Obfsproxy for Windows?

Thanks.
