Problems installing a service in Windows Server

Are you running Prompt as an administrator? If it is windows 8 I suggest you try doing the same operation on a window 7.

But I already had some problems with installutil.exe ... so I do the following:

Add the reference System.Configuration.Install to your service in visual studio. In Main.cs or Program.cs (depends on your application) put the following code:

static void Main(string[] args)
{
    if (Environment.UserInteractive)
    {
        string 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
    {
    //aqui é seu codigo para rodar o serviço normalmente.
        ServiceBase[] servicesToRun = new ServiceBase[] 
                          { 
                              new ValidatorService() 
                          };
        ServiceBase.Run(servicesToRun);
    }
}

Now you just call in the cmd generated program: Servico.exe with the --install argument to install the service ... to uninstall use the --uninstall. And now you can throw out installutil.exe

By deduction, it seems that the G:\ unit corresponds to a network mapping . In this case, the installation will actually fail.

Try to move all dependencies to a local drive ( C: ) and install the service into that directory.

If G:\ is a mapping to a drive of the local machine itself, use the original path to which the mapping points to register the service executable. Example:

installutil.exe c:\meu_mapeamento\iERP\(...)\iServicos.exe
