Another Chef Windows service issue?

Hi,
With Tim’s help, I was able to fix the windows service issue earlier. Now I am running into other issue,

windows_package “Some Client” do
source "http://localhost/example.exe"
installer_type :custom
options "/verysilent /norestart /dir=c:\tools\\example"
action :install
end

when I run chef-client from commandline (ie manually ),it is fine. when I run it as windows service, I got this error
