RailsアプリケーションをWindowsサービスとして登録したい

Question

前提・実現したいこと

Rails製文字列抽出サーバーchupa-text-http-serverをWindowsサービスとして登録、管理したい。
Bitnami Redmineのサービスマネージャーでサービスの開始／停止がしたい。

当方、Rubyのことはさっぱりわかりません…

環境
Windows7 x64
Bitnami Redmine 4.0.5
Redmineは"C:\Bitnami"にインストールしてあります。
RubyはBitnami Redmineの物を使用

試したこと

use_redmine.batを起動しchupa-textの導入、起動を確認

cd C:\Bitnami
git clone https://github.com/ranguba/chupa-text-http-server.git
cd C:\Bitnami\chupa-text-http-server
bundle install
rails s

ネットで検索した情報だと"thin"でサービス化できるようなので
Gemfileにgem 'thin'を追加してthin startでサーバー起動を確認

bundle install
gem uninstall -I eventmachine
gem install eventmachine --platform ruby
thin start

サービス登録

"C:\Bitnami\redmine/apps/redmine\scripts\winserv.exe" install "ChupaText" -start auto "C:\Bitnami\redmine\ruby\bin\ruby.exe" "C:\Bitnami\redmine/apps/redmine\htdocs\bin\thin" start -e production -c "C:\Bitnami\chupa-text-http-server" -p 3000 -a 127.0.0.1

サービス登録されますが起動できません。
コマンドを分解して実行すると下記のエラーが発生します。

C:\Bitnami\chupa-text-http-server>"C:\Bitnami\redmine\ruby\bin\ruby.exe" "C:\Bitnami\redmine/apps/redmine\htdocs\bin\thin" start -e production -c "C:\Bitnami\chupa-text-http-server" -p 3000 -a 127.0.0.1

下記だと起動するので環境やコマンドのつなぎ方が問題なのかなと思っています。

thin start -e production -c "C:\Bitnami\chupa-text-http-server" -p 3000 -a 127.0.0.1

分かる方助言お願いします。
