+### Prefer 32-bit setting
+
+The **Prefer 32-bit** setting in the **Build** page of the project designer for .NET Framework 4.5 or later projects handles the case where you're building the `AnyCPU` configuration, but you want your application to run in 32-bit mode when it's executed on platforms that support both 32-bit and 64-bit modes. If you enable the checkbox, the `PlatformTarget` build property is set to `anycpu32bitpreferred`. See comments on the [PlatformTarget](/dotnet/csharp/language-reference/compiler-options/output#platformtarget) for C# and [/platform](/dotnet/visual-basic/reference/command-line-compiler/platform) for Visual Basic.

 ### Manually editing the project file
 
 Sometimes, you need to manually edit the project file for some custom configuration. An example is when you have conditions that can't be specified in the IDE, such as a reference that is different for two different platforms, or an assembly that must be registered for a particular platform in order to expose it to COM. The tool that processes the project file is [MSBuild](../msbuild/msbuild.md).
