 The properties for all projects that target the 64-bit platform are updated, and the next build of the project will be optimized for 64-bit platforms.
 
+> [!NOTE]
+> The **Win32** platform name is used for C++ projects, and it means **x86**. Visual Studio considers both project-level platforms and solution-level platforms, and the project platforms come from the language-specific project systems. C++ projects use **Win32** and **x64**, but the solution platforms use **x86** and **x64**. When you choose **x86** as the solution configuration, Visual Studio selects the **Win32** platform for C++ projects. To see both project-level platform and solution-level platform settings, open **Configuration Manager** and note the two platform settings. The solution-level platform is shown in the **Active solution platform** dropdown, and the table shows the project-level platform for each project.

 ## Target platforms in the Project Designer
 
 The **Project Designer** also provides a way to target different platforms with your project. If selecting one of the platforms included in the list in the **New Solution Platform** dialog box does not work for your solution, you can create a custom configuration name and modify the settings in the **Project Designer** to target the correct platform.
