Hi,
There are 2 ways you can create a package for the clients one is a .exe file and the other is msi file. Once this package is created you can keep it aat a centralised location so that all the clients have access to it. The client can download the package on to their machine and go ahead with the installation. I am attaching a screen shot for the same.
In case you keep the option checked for "Create a single.exe file for this package" then it will create a single.exe package and if you uncheck it it will create a msi package.
