System.InvalidOperationException was unhandled HResult=-2146233079 Message=Unable to create new service: ChromeDriverService

I am trying to use Selenium Grid and C# to remotely control a Chrome browser. It used to work but since I installed a new Windows image on my machine B, it does not anymore. However, I am able to use Selenium locally on both computers, so I think it is not a chromedriver problem. For remote control, I run the following commands in machine A and machine B respectively:

java -jar C:\Users\FlcUser\Downloads\selenium-server-standalone-3.141.5.jar -role hub -host 10.1.1.14

java -Dwebdrive.chrome.drive="C:\Temp\chromedriver.exe" -jar C:\Temp\selenium-server-standalone-3.141.5.jar -role node -hub http://10.1.1.14:4444/grid/register

The node is successfully registered and then I run this C# code (I don't know if what I have commented is necessary but it doesn't change the error):

ChromeOptions options = new ChromeOptions();
        //options.BinaryLocation = "C:\\Temp\\chromedriver.exe";
        IWebDriver driver = new RemoteWebDriver(new Uri("http://10.1.1.14:4444/wd/hub"), options.ToCapabilities(), TimeSpan.FromSeconds(180));

I get this error:

Unable to create new service: ChromeDriverService

I have read a lot about it, and I tried many things. I updated everything. I've made sure that my chromedriver version is compatible with my browser and I also have the last version of Java (https://java.com/en/download/, in both machines).

These are the logs I get in cmd:

Machine A:

17:48:23.746 INFO [DefaultGridRegistry.add] - Registered a node http://10.24.25.237:19016
17:50:19.814 INFO [RequestHandler.process] - Got a request to create a new session: Capabilities {browserName: chrome, goog:chromeOptions: {}}

Machine B:

21:48:31.497 INFO [ActiveSessionFactory.apply] - Capabilities are: {
"browserName": "chrome",
"goog:chromeOptions": {}}
21:48:31.497 INFO [ActiveSessionFactory.lambda$apply$11] - Matched factory org.openqa.selenium.grid.session.remote.ServicedSession$Factory (provider: org.openqa.selenium.chrome.ChromeDriverService)

And this is the exception Visual Studio throws:

System.InvalidOperationException was unhandled

       at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
       at System.Threading.ThreadHelper.ThreadStart()
  InnerException: 

Finally, I have tried the same with other computers and I got the same error, so I am doing wrong. I think it is related with Java or chromedriver because I used to run this VS Code solution without problems. I updated also the libraries in Visual Studio via NuGet.

How can I solve this?

The issue seems to be in the command you have used to start the Selenium Grid Node which instead of being:

java -Dwebdrive.chrome.drive="C:\Temp\chromedriver.exe" -jar C:\Temp\selenium-server-standalone-3.141.5.jar -role node -hub http://10.1.1.14:4444/grid/register

Should have been:

java -Dwebdriver.chrome.driver=C:/Temp/chromedriver.exe -jar C:/Temp/selenium-server-standalone-3.141.5.jar -role node -hub http://10.1.1.14:4444/grid/register

Note A: The Key is webdriver.chrome.driver but not webdrive.chrome.drive

Note B: Ensure that the ChromeDriver binary on the Grid Node is placed at C:/Temp/
