 # Installing machine learning components without internet access
 
-Because the R and Python components provided with SQL Server 2016 and SQL Server 2017 are open source, Microsoft does not install R or Python components by default.

-Instead, we provide the related installers and bundled packages as a convenience on the Microsoft Download Center and other trusted sites. You must consent to the appropriate license, and then SQL Server setup installs R or Python components for you.

 Typically, setup of the machine components used in SQL Server 2016 and SQL Server 2017 requires an internet connection. When SQL Server setup runs, if you have selected any of the machine learning options, setup checks for the Python or R installers, as well as any other required components.

 ### Step 1. Obtain additional installers
 
-For **R** in SQL Server 2016 and SQL Server 2017, you'll need to get two different installers. The SQL Server setup wizard ensures that they are installed in the correct order.
+**For R**
+
+The R language is supported in both SQL Server 2016 and SQL Server 2017. Two different installers are required, for open source and propretary components. The SQL Server setup wizard ensures that they are installed in the correct order.
 
 + Installers with **SRO** in the name provide the open source components.
 + Installers with **SRS** in the name contain components provided by Microsoft, including those for database integration.
 
-For **Python** in SQL Server 2017, download the single CAB file, and any prerequisites.
+**For Python**
+
+The Python language is supported only in SQL Server 2017. Again there are two separate installers that you must download.
+
++ Installers with **SPO** in the name are for Microsoft Python Open, and provide the open source components.
++ Installers with **SPS** in the name are for Microsoft Python Server, and contain components provided by Microsoft, including those for database integration.
+
+**How to download**
 
 1. Download the installers from the [Microsoft Download Center sites](#installerlocs) onto a computer with internet access, and save the installer rather than running it.
 2. Copy the installer (CAB) files to the computer where you intend to install machine learning components.
