Missing Create GUID in Visual Studio Enterprise 2017?

Mine was in Microsoft Visual Studio 11.0 instead of the Microsoft Visual Studio

Under c:\program files (x86) there are several MVS folders and each with a Common7 folder and some with Tools folder.

In one of then guidgen.exe is hiding.

Replace the links from Tools -> External Tools -> Create GUID, for example in my case

c:\program files (x86)\Microsoft Visual Studio 11.0\Common7\Tools


Please follow troubleshoot section in this documentation. https://social.technet.microsoft.com/wiki/contents/articles/33047.create-guid-tool-in-visual-studio.aspx

If the tool does not appear under the Tools menu, click Tools > External Tools (see image above). It may be that the tool was not registered correctly within the IDE. Using the External Tools window, we can add a reference to guidgen.exe.
