WebDriverException: unknown errors; "chrome failed to start” and “Failed to create a Chrome process”

After installing Katalon Studio v.5.8.2 to a co-workers laptop, when trying to run the test, test fails with this exception

Test FAILED because (of) (Stack trace: com.kms.katalon.core.exception.StepFailedException: Unable to open browser with url: ‘’ (Root cause: org.openqa.selenium.WebDriverException: unknown error: chrome failed to start (Driver info: chromedriver=2.35.528161(5b82f2d2aae0ca24b877009200ced9065a772e73),platform=Windows NT 10.0.17134 x86_64) (WARNING: The server did not provide any stacktrace information) Command duration or timeout: 104 milliseconds Build info: version: ‘3.7.1’, revision: ‘8a0099a’, time: ‘2017-11-06T21:07:36.161Z’ Driver info: driver.version: CChromeDriver)

After updating chromedriver to 2.43 I get a slightly different message

Test FAILED because (of) (Stack trace: com.kms.katalon.core.exception.StepFailedException: Unable to open browser with url: ‘’ (Root cause: org.openqa.selenium.WebDriverException: unknown error: Failed to create a Chrome process. (Driver info: chromedriver=2.43.600210(68dcf5eebde37173d4027fa8635e332711d2874a),platform=Windows NT 10.0.17134 x86_64) (WARNING: The server did not provide any stacktrace information) Command duration or timeout: 156 milliseconds Build info: version: ‘3.7.1’, revision: ‘8a0099a’, time: ‘2017-11-06T21:07:36.161Z’ Driver info: driver.version: CChromeDriver)

Both messages happen with Chrome 70, and the same thing happens when I revert to Katalon Studio v.5.8.0.

Since this is not my machine, I am unable to change Chrome version.

What could be causing the problem?

The problem was solved by running Katalon as administrator.
