是的，您可以并排安装多个版本的 Visual Studio.但请先安装较低版本.

Yes you can install multiple versions of Visual studio side by side.But install the lower versions first.

如果您使用 Visual Studio 2013 打开在 Visual Studio 2012 或带有 Service Pack 1 (SP1) 的 Visual Studio 2010 中创建的解决方案，您可以稍后在旧版本中再次打开和修改解决方案，只要您没有未实现任何特定于 Visual Studio 2013 的功能.

If you use Visual Studio 2013 to open a solution that was created in Visual Studio 2012 or Visual Studio 2010 with Service Pack 1 (SP1), you can later open and modify the solution again in the older version as long as you haven't implemented any features that are specific to Visual Studio 2013.
