How to I create a Windows service from a script, run as administrator -

i have windows installer script windows application i'm delivering customers. want have application installed windows service.

i've been reading on various ways this. closest i've found can command sc.exe described in create windows service executable here @ stackoverflow, command requires running administrator, far can tell, requires submitting administrator's password.

in build script, there's no way right-click , "run administrator".

is there way build script (i'm using company's installation packager this, uses ant-like xml build files command , statements -- so, running @ windows command line). if figure out command-line implementation customers can use give them package.

thanks tips. scott
