sc create <servicename> binpath= "<pathtobinaryexecutable>" [option1] [option2] [optionN]
The trick is to leave a space after the = in your create statement, and also to use ” ” for anything containing special characters or spaces.
It is advisable to specify a Display Name for the service as well as setting the start setting to auto so that it starts automatically. You can do this by specifying DisplayName= yourdisplayname and start= auto in your create statement.
Here is an example:
C:\Documents and Settings\Administrator> sc create asperacentral
binPath= "C:\Program Files\Aspera\Enterprise Server\bin\Debug\asperacentral.exe"
DisplayName= "Aspera Central"
start= auto
If this worked you should see:
[SC] CreateService SUCCESS
