Creating an administrative install of SSDT update for Visual Studio 2013
Since we are offering our VS2013 update via the Visual Studio update channel, there aren't any specific instructions on how to get the download if you need to create an administrative layout. You may need to do this if your firewall or proxy settings do not allow some computers to access the download center.
You can either choose the update from within visual studio on a machine that has internet access and instead of running the SSDTSetup.exe, download it locally; or you can use this fwlink to get to the download: http://go.microsoft.com/fwlink/?LinkID=393521
*Disclaimer - this FWLink may change in the future, so while it works for the July update, that doesn't mean it will work for upcoming updates
Once you have the SSDTSetup.exe file downloaded locally, you can run the administrative layout command on a computer with internet access to create a copy that you can burn or place on a share
Run the following command using an administrator command prompt (cmd.exe run as administrator):
SSDTSetup.exe /layout <destination>
Where <destination> is the location you wish to create the administrative install point (e.g on a USB drive, a LAN drive or other accessible location).
To use the install point once created on a computer without internet access, simply run SSDTSetup.exe from the <destination> location with no arguments. This will use the install point rather than attempting to download new copies of the relevant chained components.
