Unable to work on Chrome

Hi,

Am getting an error "Time out expired after launching application. The requested object "//BrowserApplication[@browsertype="Google Chrome"]" was not found within the timeout of 30 seconds. Ensure that the "Silk Test Chrome Extension" is installed and enabled. To see your Chrome extensions, go to chrome://extensions."  I am using below Silk Test and Chrome versions. Could some one help on this.

Silk Test 17.5 Hot fix

Chrome 52 / Chrome 53.

Thank You
