Para instalar um serviço, execute o comando InstallAndStart da seguinte maneira:
SystemControl.InstallAndStart(
"apache",
"Apache Web Server",
@"""c:\apache\bin\httpd.exe"" -k runservice"
);
Verifique se a conta que está executando o programa tem permissão para instalar serviços. Você sempre pode 'Executar como administrador' no programa.
Também incluí vários comandos para acesso não-API que não instalam ou removem serviços, mas você pode listá-los e controlar vários (iniciar, parar, reiniciar). Você realmente só precisa elevar as permissões para instalar ou remover serviços.
Existem alguns comandos para obter e definir variáveis de ambiente, como OPENSSL_CONF
ou TEMP
. Na maior parte, os parâmetros e nomes de métodos devem ser bastante auto-explicativos.
