Windows SBS 2011 Standard user software installation

I have Windows SBS 2011 standard, I want to install softwares on all user computers connected to the server.  Is there any easy way to do that without having to log into each users account?  Can I just install it from the server or do i have to install it on each computer under administrator or something?  I really have no idea never done anything like this before?  

Thanks for any help
