My device situation is odd and there is nothing I can do about it.

Machine #1 has an internet connection but I do not own or control machine #1.  I am merely permitted the use of it.  I was able to download the Essential's wlsetup-web.exe file from the Microsoft website onto a USB drive using machine #1.  I then moved the file from the USB drive to machine #2.  Machine #2 has my activated copy of Windows 8 but it does not have an internet connection (and it must not have one--there is a reason for that).  When I attempt to install Essentials I get the obvious error message that I need an internet connection.  What can I do?

I was able over the phone to activate Windows 8 on machine #2 since it involves just receiving a number and using that to unlock files already present on my hard drive within the OS.  I suspect with Essentials the situation is different, that wlsetup-web.exe does not contain the files, that it initializes a process to copy and then install more files--fine.  Is there any other way to legally obtain the files, to get them onto a machine which itself does not have an internet connection?  E.g. can I temporarily not copy but actually install Essentials onto a USB drive connected to machine #1 and then complete the installation onto machine #2 which has my Windows 8?  How?  E.g. can Microsoft make the files available to me in some other form?   Is there some other way?  Is there no way at all?  It seems silly that I can install Windows 8, that I can activate it, that I could obtain wlsetup-web.exe and yet cannot obtain Essentials.
