Hi,

when I try to create a Build an run it on Local Machine, I get the following three errors:

  1. “Exception: Failed to locate env variables VS140COMNTOOLS or VS120COMNTOOLS. Utility.GetVSVersion () (at C:/buildslave/unity/build/PlatformDependent/WinRT/SharedSources/CSharp/Utility.cs:623) ApplicationLauncherImpl.Build () (at C:/buildslave/unity/build/PlatformDependent/MetroPlayer/Extensions/Managed/ApplicationLauncher.cs:200) ApplicationLauncher.BuildAndRunOnSingle (BuildLaunchPlayerArgs args, WSASDK wsaSDK, WSABuildAndRunDeployTarget deployTarget) (at C:/buildslave/unity/build/PlatformDependent/MetroPlayer/Extensions/Managed/ApplicationLauncher.cs:60) ApplicationLauncher.BuildAndRun (BuildLaunchPlayerArgs args) (at C:/buildslave/unity/build/PlatformDependent/MetroPlayer/Extensions/Managed/ApplicationLauncher.cs:50) UnityEditor.WSA.BuildPostprocessor.LaunchPlayer (BuildLaunchPlayerArgs args) (at C:/buildslave/unity/build/PlatformDependent/MetroPlayer/Extensions/Managed/ExtensionModule.cs:122) UnityEditor.PostprocessBuildPlayer.Launch (BuildTargetGroup targetGroup, BuildTarget buildTarget, System.String path, System.String productName, BuildOptions options, UnityEditor.BuildReporting.BuildReport buildReport) (at C:/buildslave/unity/build/Editor/Mono/BuildPipeline/PostprocessBuildPlayer.cs:216) UnityEditor.HostView:OnGUI()”

  2. “Exception: Failed to locate env variables VS140COMNTOOLS or VS120COMNTOOLS.”

  3. “UnityEditor.BuildPlayerWindow+BuildMethodException: Build failed with errors. at UnityEditor.BuildPlayerWindow+DefaultBuildMethods.BuildPlayer (BuildPlayerOptions options) [0x001b9] in C:\buildslave\unity\build\Editor\Mono\BuildPlayerWindowBuildMethods.cs:162 at UnityEditor.BuildPlayerWindow.CallBuildMethods (Boolean askForBuildLocation, BuildOptions defaultBuildOptions) [0x00050] in C:\buildslave\unity\build\Editor\Mono\BuildPlayerWindowBuildMethods.cs:83 UnityEditor.HostView:OnGUI()”

I tried Unity 2017.1.0b6 (64-bit) and Unity 5.6.1f1 (64-bit) on Windows 10 Pro 64 bit with Visual Studio 2017 Community installed and Visual Studio 2015 Tools for Unity installed.

Any idea how to solve this problem?

Thanks in advance

Solved 1 and 2 by reinstalling Unity and VS.

The quick fix that worked for me (using VS 2017 community edition) is add those environment variables myself:
VS140COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\Tools
