Visual Studio 2010 disappears after installing Visual Studio 2013 - visual-studio-2010

First I have installed Visual Studio 2013 Professional, then I installed Visual Studio 2010 Ultimate.
How to run Visual Studio 2010?
In Visual Studio 2013 - No problem.
But in Visual Studio 2010 - Visual Studio 2010 disappears.

The older version must be installed first, since the installation does not downgrade.
First install the 2010 version and then to 2013.

My question is partly in relation with my earlier question
Thanks
Visual Studio 2015 can co-exist with visual Studio 2017. Since you have install Visual Studio 2015, and just start it from
"C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe"
Sure, create shortcut on your desktop for your next time......
