We designed the Visual Studio 2017 installer to work well in a wide variety of network and machine conditions.
- The new workload-based model means you'll need to download far less than with previous versions of Visual Studio: as little as 300 MB for the smallest installation;
- Compared to a generic "ISO" or zip file, we download only the packages you need for your machine. For example, we don't download 64-bit files if you don't need them;
- During the installation process, we try three different download technologies (WebClient, BITS and WinInet) to minimize interference with anti-virus and proxy software;
- The files you'll need to install Visual Studio are distributed on a global delivery network, so we can get them to you from a local server.
We recommend that you try the Visual Studio web installer—we think you'll find it a good experience.
If you want to install a single instance of Visual Studio 2017 but your internet connection is unavailable or unreliable, see Install Visual Studio 2017 on low bandwidth or unreliable network environments. You can use the command line to create a local cache of the files you need to complete an offline install. This process replaces the ISO files available for previous versions.
If you are an enterprise administrator who wants to perform a deployment of Visual Studio 2017 to a network of client workstations that are firewalled from the internet, see our Create a network installation of Visual Studio 2017 and Special considerations for installing Visual Studio in an offline environment pages.
