    capa.setBrowserName("chrome");
    File file = new File("path\\to\\file\\.exe"); 
    URL server = new URL("http://ip_of_remote_pc:4444/wd/hub"); 

    ChromeOptions options = new ChromeOptions();
    options.setBinary(file);   //Sets the path to the Chrome executable
    capa.setCapability(ChromeOptions.CAPABILITY, options);
    driver2 = new RemoteWebDriver(server, capa); //launch the application
    System.out.println("launching application in remote PC");
    driver2.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);   
    System.out.println("Application launched");

Just add the following ChromeOptions it will solve the problem,

ChromeOptions options = new ChromeOptions();
options.addArgument("--headless");
options.addArgument("--no-sandbox");  // Bypass OS security model
options.addArguments("--disable-gpu"); // applicable to windows os only
