running vstest (Windows 10, TC 12) in isolation

oes running vstest.console.exe /InIsolation require Microsoft Visual Studio be inslalled on the machine it is running?  I built a package and tested it on my machine which worked fine.  When I copied the TestWindow directory (and all other assorted files) to another VM it did not run.  When I did the same thing to a third VM it worked fine.

 

So I am wondering whether Visual Studio must be installed, you cannot just copy the test window to a new machine and run it.

 

So on the two machines where it works, both have this directory:

C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow

 

On the machine where it does NOT work, there is no directory C:\Program Files (x86)\Microsoft Visual Studio 11.0\

(nor in Program Files\)
