WinAppDriver issue

Issues/Bugs
1

I am trying to run a Calculator app – on windows 10. I have started appium from command prompt (V1.7.1); I am getting below message in eclipse when I run

“Exception in thread “main” org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command. Original error: Could not verify WinAppDriver install; re-run install”

My code is below
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(“app”, “Microsoft.WindowsCalculator_8wekyb3d8bbwe!App”);
capabilities.setCapability(“platformName”, “Windows”);
capabilities.setCapability(“deviceName”, “WindowsPC”);
CalculatorSession = new RemoteWebDriver(new URL(“http://127.0.0.1:4723/wd/hub”), capabilities);
CalculatorSession.manage().timeouts().implicitlyWait(2, TimeUnit.SECONDS);
CalculatorSession.findElementByName(“Seven”).click();
CalculatorSession.findElementByName(“one”).click();

I tried below code too and same issue is coming up

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(“app”, “Microsoft.WindowsCalculator_8wekyb3d8bbwe!App”);
capabilities.setCapability(“platformName”, “Windows”);
capabilities.setCapability(“deviceName”, “WindowsPC”);
CalculatorSession = new WindowsDriver(new URL(“http://127.0.0.1:4723/wd/hub”), capabilities);

        CalculatorSession.manage().timeouts().implicitlyWait(2, TimeUnit.SECONDS);
       CalculatorSession.findElementByName("Seven").click(); 
        CalculatorSession.findElementByName("one").click();

the above issue is solved via installing 0.9 beta of winappDriver
