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

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Visual Studio 2010 Service Pack 1(SP1)中创建的解决方案，则以后您可以在较旧的版本中再次打开并修改该解决方案，前提是您没有没有实现特定于Visual Studio 2013的任何功能.

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.
