Hi,  
I am trying to create and register a windows service with the following  
code.

require “rubygems”  
require “win32/service”  
include Win32  
svc = Service.new(:service\_name =\> “rajiv\_service\_name”)

Error:  
C:/Ruby/lib/ruby/gems/1.8/gems/win32-service-0.7.1-x86-mswin32-60/lib/win32/service.rb:368:in  
`initialize': Access is denied. (Win32::Service::Error) from C:/Users/Rajiv/Documents/NetBeansProjects/MusicClockService/lib/register_bar_1.rb:9:in`new’  
from  
C:/Users/Rajiv/Documents/NetBeansProjects/MusicClockService/lib/register\_bar\_1.rb:9

I tried changing to:

svc = Service.new(:service\_name =\>SERVICE\_NAME,  
:service\_start\_name =\> “HOME\Rajiv”,  
:password =\> “my\_pwd” )

but it still did not work.

Thanks,  
Rajiv

Just adding to the previous post, if it helps:

- I installed the win32-services gem using gem install win32-service  
–platform=mswin32
- The doc. says that only :service\_name is mandatory. So, it is bit  
surprising that it does not work
- User Rajiv is Administrator

Is the prompt from where are you invoking the ruby script running with  
elevated privileges?

On Vista and 7 even when user is Administrator it needs UAC elevation  
to properly modify registry related to system

Thanks Luis !  
I run the file from netbeans 6.8 and you set me on the right path.  
Based on your answer, I poked about a bit and found  
[[Netbeans issue - JRuby - Ruby-Forum](http://www.ruby-forum.com/topic/198439#905647)] where Philippe Rubyeye  
provided an easy alternative(Running Netbeans as administrator).
