Jruby gem error win32-service for rsense

I am trying to install Rsense, I am following the directions from here Rsense Docs

RSENSE_HOME is set but i cannot install the jruby win32-service to complete the steps to have the rsense service started at boot.

This is the full error, I also ran as error suggested specifying jruby version. Any ideas on completing the install?

C:\Users\RenshawFamily>echo %RSENSE_HOME%

win32-service uses C extensions. Gems that use C extensions are generally not compatible with JRuby, although there are efforts being made to address that - see here for background

Are you able to use MRI/CRuby for your project?

Or you could use a java based service management lib, but then that might not work with emacs/rsense.

Or you could roll up your sleeves and make win32-service JRuby compatible!

I had the same problem when installing the win-32-service gem. This solved it:

gem install win32-service --platform=mswin32

So your command should probably be

jruby -S gem install win32-service --platform=mswin32

although I'm guessing here.
