You can make a Microsoft Windows Installer file (.msi) and use group policy or SMS to deploy it.
The MSI file can answer all the questions that the install program asks.
Or, if you can't use group policy or SMS to deploy it, make your MSI file and save it to a shared folder on the server and use a login script to start the MSI file.
Or, if you cannot do that, do as the Pradeep suggested. Make your MSI file, save it to a shared folder on the server, and have your users install it. They can be novices. That's OK because all thy have to do is double click on the MSI file. (Of course, this assumes that your users have permission to install.)
A free tool for making and modifying MSI files can be found at http://users.cyberone.com.au/dbareis/makemsi.htm
If the users don't have permission to install, and you can't do any of the previous suggestions, go to each machine, sit down, and install it. Use the time you have while sitting in front of each machine to justify whatever investment it will take to get to the point that you can use group policy and SMS.
