TeamCity can not start MSTest.exe or vstest.console.exe

I am getting this error when I try to run unit tests via teamcity MyTeamCity version is 9.1 and I am using Visual Studio 2015. If I change the name of MSTest.exe or vstest.console.exe it throws another error about finding the files. Also I think the problem is not about my project version, because I could run MSTest.exe an vstest.console.exe with my test dll via command line. I have already tried to install visual studio 2013 test agents but I got same error when I tried to run MSTest.exe.

MSTest executable: C:\Program Files (x86)\Microsoft Visual Studio
14.0\Common7\IDE\MSTest.exe Command line params: [[/testcontainer:C:\TeamCity\buildAgent\work\6028ae3d00a3d06d\WebApi.Test\bin\Release\WebApi.Test.dll]

How ever this works fine:

14.0\Common7\IDE\ MSTest.exe" /testcontainer:"C:/TeamCity/buildAgent/work/6028ae3d00a3d06d/WebApi.

/resultsfile:C:\TeamCity\buildAgent\temp\build

And I'm getting this error when I try to use vstest.console.exe:

On the other hand this works fine via console:
