How to resolve "'installutil' is not recognized as an internal or external command, operable program or batch file."?

Just tried to run an application via the following:

I have browsed to the directory with an app WindowsService1.exe in it, then tried the command Installutil WindowsService1.exe but got the following error...

As VS has only been installed for a day or two I'm worried that something may be wrong with that install as it should recognise installutil.

Are there some basic diagnostics I can perform to ensure that VS Command Prompt is finding all the programs that it should ?

EDIT

If i run PATH in the command prompt I see the following:

This is a tiny bit off-topic but I've stopped using InstallUtil to install my services. It's is really easy to just add it to the service itself. Add a reference to System.Configuration.Install (not available in the Client Profile editions if I remember right) and then update your Main()-function in Program.cs like this.

static void Main(string[] args) {
    if (Environment.UserInteractive) {
        var parameter = string.Concat(args);
        switch (parameter) {
            case "--install":
                ManagedInstallerClass.InstallHelper(new[] { Assembly.GetExecutingAssembly().Location });
                break;
            case "--uninstall":
                ManagedInstallerClass.InstallHelper(new[] { "/u", Assembly.GetExecutingAssembly().Location });
                break;
        }
    } else {
        ServiceBase[] servicesToRun = { 
            new Service1() 
        };
        ServiceBase.Run(servicesToRun);
    }
}

Then you can just call WindowsService1.exe with the --install argument and it will install the service and you can forget about InstallUtil.exe.

This is what I have done to make it go away:

1. Found where installutil resides on my PC. In my case it was C:\Windows\Microsoft.NET\Framework\v4.0.30319

2. Opened a command prompt as an Administrator and changed current directory to above: 'cd C:\Windows\Microsoft.NET\Framework\v4.0.30319'

3. Then entered: 'installutil C:\MyProgramName.exe'

Interestingly, prior to above solution I tried different options, among them adding C:\Windows\Microsoft.NET\Framework\v4.0.30319 to the System Path variable, but it still could not find it.

Wish you all smooth installation.

InstallUtil.exe is typically found under one of the versions listed under C:\Windows\Microsoft.NET\Framework.

In my case it is under v4.0.30319.

You could just check your path:

echo %PATH%

should give you a list of directories searched for executables.

Found a solution on bytes.com

The code to install a service:

@ECHO Installing Service...
@SET PATH=%PATH%;C:\Windows\Microsoft.NET\Framework\v4.0.30319\
@InstallUtil  C:\Unlock_4_Service\bin\Debug\Unlock_4_Service.exe
@ECHO Install Done.
@pause

@InstallUtil <.exe file path of your windows service>

Code to uninstall the service

@ECHO Installing Service...
@SET PATH=%PATH%;C:\Windows\Microsoft.NET\Framework\v4.0.30319\
@InstallUtil /u C:\Unlock_4_Service\bin\Debug\Unlock_4_Service.exe
@ECHO Uninstall Done.
@pause

@InstallUtil /u <.exe file path of your windows service >

Save the 2 files as service_install.bat and service_uninstall.bat

Run the files as administrator, every time you have to install or uninstall the service.

Before Installing service using command line...

use 2 steps:

1. cd C:\Windows\Microsoft.NET\Framework\v4.0.30319
2. InstallUtil.exe Path\MyWindowsService.exe
