'installutil' is not recognized as an internal or external command, operable program or batch file.

You get this error when you type 'installutil.exe' in a command prompt.
Reason: .net folder path is not set in the 'PATH' variable because of which location of installutil.exe was not found.


a) Use the visual studio command prompt, it will work there
b) Set .NET folder path in system's 'PATH' variable . Then try it should get the path of 'installutil.exe' and you can use it directly in any command prompt.
