error MSB8020解决方法

error MSB8020: The builds tools for v120 (Platform Toolset = 'v120') cannot be found. To build using the v120 build tools, either click the Project menu or right-click the solution, and then select "Update VC++ Projects..."

下载Reactivision后用VS2012打开后运行报错，解决方法：

项目->属性->常规->平台工作集，将平台改为VS2012  (v110)后即可成功运行
